I'm here almost 7 years later but I guess it is perfect timing!
k
when your chemistry teacher can't teach... crashcourse saves you
sahi ho
true
yes^
Speed Demo that's so true 😂
LITERALLY SO TRUE
And sadly Chemistry is a subject that you absolutely NEED a good teacher for, someone who knows what they are doing
This 11 minute video taught me more than 6 hours of lecture... No wonder our education system is circling the drain
JohnWayne2122 which country are you from? I'm from India and India's education system is trash
Please don't break their dreams.
Also, don't tell them the production cost and all the people behind the scene who made even one episode possible.
And how that in no shape or form can compare to the resources that are put in a school classroom. Except if the student/pupil hasn't paid a fortune to go in a private top tier school with the best teachers and resources available for their privileged education.
@John Smith exactly
@John Smith i downloaded it but i can't do a single question. Am in high school though.
I agree . so much time and this video hits everything
God bless "Crash Course".
The reason I pass my science tests.
Who?
@ammar siddiqui But this channel is CrashCourse, I don't see any Crash Course here.
I was going to make a sodium joke....but Na
Hassaan Haider omg why
Here's a question... Who's the Eskimo cousin of Agent 007?
Ha!!
can u finish the joke?
ozpo poalluza that is the joke
Hey Hank, whenever you have a minute, PLEASE CORRECT THE ERROR at 10:12. Dehydrogenation is NOT the removal of a water molecule. Rather, it is the removal of hydrogen. Thank you for yet another awesome video!
I wanted to say that as well. Good thing that someone else also noticed that!
Same I thought I was the only one lol
Park City me too!!! LOL. :)
he didn't say that, said it was the removal of hydrogen 10:09
I believe that was an editing error on thought cafe's part
This has got to be the most helpful channel on UA-cam.
Tom Parker AMEN!!!!
i left this playlist playing and listened to it all night. i woke up at 5 in the morning thinking of hydrocarbons before i realised u were speaking to me through the speakers. weird night.
nancy charlton where does he talk about the reactions
Sneaky way to remember prefixes:
Monkeys (Meth)
Eat (Eth)
Peeled (Prop)
Bananas (But)
+PartyGardi Film Studios
Mine was Me Eat Peanut Butter
+Tricell CEO I had heard this stated similarly as "Mary Eats Peanut Butter" but I think PartyGardi's example is more visual.
+PartyGardi Film Studios
Here's the one I learned (goes up to 10):
"Many Enemy Planes Bomb Pearl Harbor Help Our Nation Defeat enemy planes" (Meth- Eth- Prop- But- Pent- Hex- Hept- Oct- Non- Dec-)
+Skyler Trieu I think you're the first person I've seen to bother with a mnemonic for anything past pentane. I usually can just remember the (Latin?) prefixes.
This is helpful but I need to memorise until the eighth one.
My teachers sure could learn from this
Lol

How a Crash Course on Astronomy. .....
Patrick Sparks
Well, I guess I can learn Chinese now.
Patrick Sparks Chinese is the language of life? Should have known.
CrashCourse Hank doesn't have a penis.
I know Im 2 years late but you need a medal.
I'm struggling so much with this at school 😑😑😑 but now I kinda get it 😊 a good teacher really makes a difference
The way he says Organic Chemistry summarizes how everyone feels about Organic Chemistry :D
Poor Organic Chemistry. It just wants to be loved.
it's the most interesting kind of chemistry though
Organic Chem quiz tomorrow... This is helping so far
HOW IS IT THAT I JUST FOUND THIS CHANNEL?
hank green is 2000 times better at teaching science than my dorky ass teachers!
Which class are you?
chemistry, thats why im watching this video
yes, but I mean high school right? which grade*
+epaxinc I'm in 5th grade so.......
yours teachers got to punish you
I'm so happy I didn't take organic chemistry in college :)
1 year later
I hate chemistry.
I'm serious, there is no other subject in school that I hate more (exept physics, maybe). To my defense: I blame my teachers.
But anyway, I have a chemistry exam in two days which I NEED TO PASS, or else I'm fucked.
I think the only way to do it is to binge watch the chemistry crash course videos - which is fine since they're incredibly comfortable to watch and even actually interesting. I love the way Hank explains everything as if it's not part of a huge complex random fucked-up system that I'll never get to understand. It's way easier than I thought. Thank you so so so much, Hank (and crash course team) for doing this. You're literally saving me.
So let me rephrase my first sentence: I hate the way they taught me chemistry, but I love the way crash course teaches it.
You stink then. I love science... I'm passionate for it! And I'm only 11.
aidenx lego That explains why you still love it. Wait until you're in sophomore year.
And, by the way, he's not literally saving you unless you will die without his help.
Teachers....I know what you mean...
John Sherer I loved science at 11, and I still love it at 24. I'm currently studying neuroscience in college and have been for the last 3 years. Who knows, he may get older and decide to go into more serious scientific study.
Hank Green is a UA-cam rock star.
Thank you Hank
My name is Toni and I'm 14
I am preparing for a Chemestry competition in my country(Croatia),and I just couldn't realize how to name alkanes
But now,thanks to you,I get it
Thank you Crash Course Chemestry!:)
@Ignited TNT hahaha
I wonder how many med students have watched this.
Too many.
+Gaile Viernes including me. Well, pre-med.
+Bethany Marty I'm watching this of my own volition to further my understanding of the world instead of trying to memorize information to pass a test.
+Bethany Marty Mechanical Engineering student here hehe
one right now 😢
Finally! Got to the topics that I'll study in chemistry this year. Even though it's in English(which is not my native language), I finally understood what our chemistry teacher was talking about in the past 2 months. Keep up the awesome vids, guys!
Yes! Very excited to see your series on organic chem, this episode was great! As a chemistry major myself, I always enjoyed organic chemistry, even up through the crazy advanced and drug synthesis classes, and it will be good to have a refresher of the basics lol. Your videos are excellent, don't stop making them!
my O-chem/biochem professor is really terrible at explaining things, and it doesnt help that she is european so her accent combined with choppy sentence structures and grammar make the class impossible. thank the heavens i found this channel, im going to pass the class now!
"No exceptions" - The mongol lord was so ready to bust out
Did anyone else catch the "no exceptions" bit, with the animation of the Mongol rocking in the darkness?
Comment the timing of him saying that
YES
I watched this entire series last year for my csec exams and now I'm watching them again for pre-med. Crash course is awesome and now they even have physics!! Can it get any better?
These chemistry videos are almost completely in sync to every unit I'm taking in chem this year which is so freaking convenient. Thank you Hank!
I consider this studying chemistry.
Never again will I have to bring home my heavy chemistry book to study.
I'm nearing the end of my first semester of Ochem and I really fell in love with it. I wish we had gotten to organic chem earlier in Crash Course as my final is in a few weeks. Oh well, still very happy to be able to review with Hank!
This is going to be so helpful for my organic chem course in this upcoming semester. Thanks Hank!
You managed to explain what my chemistry teacher has been struggling to teach us for the past month and half. Thank you so much!
How are people passing exams by just watching crash course? This merely touches the surface of what I get and doesn't help me at all with my exams. Is american education that easy? I do enjoy them though.
I live in the US and I use these to introduce me to things I haven't studied yet/are about to study. There's no way someone could watch this and be ready for a test. Even in the US.
Well, it gives people a starting point of they have no idea what's going on
Troll I think they're just exaggerating. They probably learnt the more complicated and advanced stuff in school or something but Crash Course helped summarise the basics which would help with the more advance stuff. I wouldn't feel safe at all going into the exam learning nothing but what is taught on Crash Course
Troll I think the name of the commenter should give you an idea about what the comment actually is.
Troll This gets me trough middle shcool here in Norway, nothing more.
Finally! Organic chemistry. I've been looking forward to this for a while.
Ok seriously everybody is exaggerating so much about his talking speed! Just pause the video if you need a moment to reflect on what he implies! If not, you can just sit back and enjoy without losing your attention because the teacher is dwelling eternally on one thing (I hate when teachers do that)
linguaphile Yeah I paused a few times and rewinded
Exactly. Who wants to click on an hour long video? It's discouraging.
Hank and John are obviously both intellectually gifted which is kind of logical since the intellectual quotient is actually a matter of genes, and yes Hank, you speak way wayy wayy too fast for my questions to settle up, but I love you because that is a more proper way to learn than that offered at school. Sincerely, I never actually follow any class at school, always daydreaming ( about people, and ants, and books, and atoms) and getting to study on my own is way easier with those videos.
"properly proper chemists"
OMG WHY DID I DISCOVER THIS NOW I HAVE A TEST ABOUT THIS TOMORROW!
This is precisely the chemistry lesson I had today. Was nice to be able to go over it by watching UA-cam instead of just reading notes :3

I've learned a TON from this video. Keep it up, Hank. I love these videos, learn more here in 10 minutes than I do in 5 months of a chemistry course at school.
Thank you for taking so much efforts for making this video and teaching us.
Hank, you're awesome and everything, but at 10:14 the slide says "Dehydrogenation - removal of a water molecule." Shouldn't this be "removal of hydrogen"?
Arun Sridharan exactly my question :( too bad you didnt get an answer bro
Its like a puzzle we got to make.
I laughed so hard on that and i don't know why!1
Just started Orgo in my uni and I'm beyond excited about these crash course videos! Thanks Hank!
A brilliantly presented chem lecture. Was highly helpful. Thanks a ton Hank!
Do crash course quantum physics/mechanics!
i owe you my survival in college hank thank soooo much!!!
Hey man, I love these videos and they're saving my college carry. Thanks a ton.
I love the energy Hank Green has in his videos
at 10:13 it says dehydrogenation is removal of a water molecule- isn't that dehydration?
+Houston Xue Dehydration refers to the removal of a water molecule, while dehydrogenation refers to the removal of simply Hydrogen (H2).
It was a typo
I just heard "welcome to organic chemistry" and the video ended
i love watching these videos as I have my science exam in two days and this is great revision for me, awesome hank!
Thank you for your videos and for proving that Chemistry is not torture. Amazing job you guys did here. Infinite thumbs up!
Dehydrogenation - you subtitled it wrong at 10:11. Not removal of water molecules.
I was going to point that out too..
Are you serious? You only realized a mistake there? If you were to take out all mistakes filled in these subtitles, you'd probably might as well write out the whole thing.
Not the captions, the actual text in the video. It said "removal of water molecules" and he said "removal of hydrogen atoms"
***** I meant the actual thing written under the title in the video. The captions are automatic, that's not what I meant.
Nah, it's ok, "subtitle" and "caption" are basically synonyms anyway. I should've been clearer.
Great wall of china--- I am the longest thing in this world..
Carbon -- Hold my bond!!
I just realized the reason so many of us learn much more from Hank and many other youtube videos. Our teachers eventhough we bash them, they try, but the manner in witch Hank explains, its like I had to hear it again but in different words and in a different order. So, language here is critical for one to understand the information.
We LOVE your videos! We watch you all the time in our homeschool! Thank you so much for these videos!
too fast but explains the intro so good :3
Go to 8:50 and change the speed to 0.5....
I was studying and reading for hours, then this perfect summation came along. It really cleared up some confusion I was having with IUPAC nomenclature. Thank you!
It's like the best refresher of High School chemistry nomenclature that I've had in a while.. and actually needed..
I went to get a snack and when I came back i heard something about meth
Hank you're either ridiculously gifted or crazy if you think organic chemistry is fun
But it's like a puzzle!!! A sometimes frustrating puzzle, but a puzzle nonetheless.
gokucrazy22 8:50 *psycho face*
this is awesome because I'm learning this at the moment.
Hi! I am biomedical engineering major and I took Organic Chemistry 1 and 2 about two years ago. These videos are so helpful for reviewing forgotten material that I'd love to see more. Is there any chance that you'll be creating more videos for organic chemistry? By the way, you guys are the best! I've been using your videos for three years now.
someone needs to make a GIF out of 8:50
What makes it so funny?
wow he sounds so drunk when on 0.5 speed
rune titan
what do you expect
seen this comment how many times in previous videos now :/
Yeah, he's definitely been on the ethanol lately.
And at 7.5 as well XD
In 2x speed he sounds like my chemistry teacher
Thank you so much for this explanation! It really makes it simpler and easier to understand.
so glad you are doing this now, right in line with my AS levels!
The nomenclature is so regular that this makes me want to write a computer program that lets you put in the name of a hydrocarbon and it will show you a 3d model.
Let's see what it does to 2-vinylnaphtalene, or [2,2,2]bicyclooctane.
This program is called ChemDraw 3D
See also: Wolfram Alpha - it can show what everything looks like.
Jason Wilkins
The former is an example of a name using nonsystematic nomenclature (because it's much easier and because, being aromatic, systematic nomenclature can't fully describe its structure), the latter an example of nomenclature you probably would miss. You'd probably eventually find some compounds for which there is as yet no known systematic nomenclature, or at least none that doesn't rely at least partially on trivial names.
Trust me, that would be one hell of a program to write... Hydrocarbons are the easiest organic compounds but there are still lots of exceptions and trivial names which aren't regular. These are just alifatic hydrocarbons, when cyclic or aromatic hydrocarbons are included, things tend to get a bit more difficult. And these are only hydrocarbons, imagine the millions of other organic compounds that contain other elements like oxygen, nitrogen, sulfur,...
That. Was. TOO. FAST!!!
under settings you can change the video's speed
I don't mind it, this is the only way I can watch educational videos without losing my attention
IM SO STOKED FOR THESE NEXT SIX WEEKS
This is helping me SO MUCH for my upcoming test
Poor Mongol
the heck do you mean?
great video but too fast
Yes OC is too large a subject
Pause the video and/or replay?
He generally is pretty quick with things. But because it's UA-cam we have the ability to pause/rewind so we just do that.
U can change the playbackb speed in that top right corner click on that three dots
May I just say how flippen' awesome you guys are. I love Crash Course! Keep it up guys-it's amazing! :) :) :)
Very well written, Edi. And as always, well presented by Hank.
This is so well explained, thank you!
Thank God! I'm definitely using this.
this was a really clear and well-made video
Just so you know, your the reason i love chemistry. Without you i don't know where i'd be. Thankyou form the bottom of my heart
الله يوفقكم لهذا العمل الجيد فعلاً إنكم تجعلوننا نحب العِلم👍
i simply love your teachings
Finally I know how these organic compounds are named! Thank you HANK and the fellow CrashCourse Team!
Bless you for making these videos and sharing your knowledge with us
Omg i had to learn all of these in a week which is impresive but said almost everything i learn in couple of mins
This guy makes Organic Chemistry so Interesting!!!!!
Clear and concise as ever.
so glad i found this just as I'm at the beginning of my ochem gcse course
I was so lost, but now understand it. Thank You!
wish I had this back when I was in high school. great stuff, quick, entertaining overview.
I was just struggling while I was trying to revise my textbook. It was super boring and I don't even want to take a look at the content. Then I popped up with the idea to search some videos and i found you. THANK YOU SOOOOOOOOOOOO MUCH for helping me to learn chemistry in an interesting way
Yay i have a test on this tomorrow! Thanks for the fun revision experience
I am currently learning this topic at School so this video was exactly what I needed!
Thank you so much for this lesson it's 1am and I'm trying to learn this as quickly as possible :)
Really thank you , your simple way to explain organic chemistry which I named it "" amusing chemistry "" was so perfect!!
Thank you for making this. It's really useful and also interesting! :D
Woohoo! From watching other chemistry videos, I have been wondering what the 3,5- and similar prefixes actually meant; but had no idea what to even google for to find out. I got the explanation in this video without even expecting it. Thank you!
eloquently put. no chance anyone could receive an explanation this concise from our current education system.
You are my favorite channel for learning
Thank you so, so much.
I'm taking notes and I got four whole pages front and back just from this video. Sick
