So I’m actually a PhD chemist who mainly does organic chemistry. I watched this in the hope to see if E and Z isomers have different reactivity to HBr. That topic was unfortunately not mentioned…. But when I listen to this, I’m no longer surprised that so many students tell me that organic chemistry is confusing. If this video here is a good representation on how it’s taught then I would probably also get confused. There is no need to introduce a major principle on addition reactions but then spending more time on special cases than on the most common one. And the foundation needs more detail. 1. It’s always like a magnet: negative charge goes towards positive charge to form an intermediate and the reaction takes place if that can easily stabilize into something more favorable. When I start explaining reactions in org chem then I first talk about electronegativity. 2. You need to first explain at length why certain carbocations are more stable than others, practice that a little bit and then apply this to addition reactions. Markovnikov derives from there automatically. Proton shifts can happen occasionally, while methyl shifts are much more rare. If you talk about that then you also need to explain why a methyl group can actually move while most other groups don’t. Better would be not to teach that at all though.
I've been following several chemistry channels (NurdRage, NileRed, Explosions&Fire) and this series has really started to connect some of the dots when they talk about the reactions they're doing - thanks so much for these videos!
Absolutely amazing video, the animations help SOOO much and the concepts were explained so well! Made for a great review. Thank you CC for once again carrying my OChem grade.
If you are on a unicycle, your best bet is to practice from a wall. When you fall, the unicycle likes to shoot outward, which could hurt one of your friends.
Hey, CrashCourse, love the videos. I'm not sure if it's been discussed already, but are there any plans for a mathematics playlist? I'd like to see that.
Thank you so much! I really racked my brain trying to make the hyperconjugation animation as clear as possible as I thought a lot of the existing references on the concept were kinda hard to understand! I'm glad to hear you found it helpful! :D
@@Arthur-ks4ho thanks so much! we use Adobe After Effects for all our Crash Course animations! If you want to see exactly how we do it, there are actually tutorials on the Thought Cafe UA-cam channel!
@@SuperAndrewlove thanks bro! ❤️ i would love to animate some reaction mechanics but i tried in adobe animate , what do you think? should i stay in adobe animate or should i switch to after effects?
@@ghaithballich5952 oh i got it, thx. the chain starts from the "yellow no 1" to the "white no 2" (from upper right to the lower left). Bromo located on Carbon no 5 that double bound with Carbon no 4. In this case, Carbon no 4 attached with ethyl group. So that it is 5-Bromo.
Markovnikov’s rule states that the electrophile attaches to the most stable part of the carbocation which consists the “least hydrogen”. Can someone back me up…
When a protic acid (HX) is added to an asymmetric alkene, the acidic hydrogen attaches itself to the carbon having a greater number of hydrogen substituents whereas the halide group attaches itself to the carbon atom which has a greater number of alkyl substituents.
UA-cam recommended me this 1 day before chemistry exam. Damn, even UA-cam cares more about me than I do.

Could have used this series back when I took ochem but now I'm in biochem so is probably useful still!
First comment!!! I'm currently studying chemistry and didn't understand organic chemistry so well, but after this series, I understood it nicely!
This video was pretty good. Understood some bits and pieces of my lecture today, but this video connected all the dots. Thank you!
Just a day after I took an exam on this...
Same XD
IB HL Chem here! My exam is in 2 weeks lol
“We can use the Ez method.”
Me: are you sure about that?
Absolutely amazing video, the animations help SOOO much and the concepts were explained so well! Made for a great review. Thank you CC for once again carrying my OChem grade.
Don't even study chemistry I just want to be more aware and knowledgeable
Same here :)
@@dredgen__ren6889 amazing 👌
Good will hunting energy right there

This is definitely one of my favorites of crash course.
I'm from the Blue Mountains in Australia! So cool to see them featured here 😃
Time to learn
9:45 I love this part lol, it's so cool, I'm actually shocked, never been taught in high school
Hehe what do you know? But isnt high school syllabus mostly fixed?
Honestly the part when she says, "okay, deep breath" is so real.
Hey, CrashCourse, love the videos. I'm not sure if it's been discussed already, but are there any plans for a mathematics playlist? I'd like to see that.
This series is really really helpful!
Seeing Organic Chemistry in a whole different view!
Not "on ze zame zide" 😆 I will remember that for the rest of my life!
Interesting and useful . Great job on animations of hyperconjugation 👍

@@SuperAndrewlove I love your animations. May I ask what program do you use to make them?

For those confused by later episodes come back to this one and pay attention to markovnikovs rule
woooohoooo......that episode was just more than a series fo me........that was amaazzzzziiiinnnnnnn........😍😍😍😍😍😍😍😍
Nice video I love it
great crash course of organic chemistry
i thank the creators.
Very good
Love that I am dutch and that there are easier way to memorize german. Entgegen --> tegen(over) ; zuzamen --> samen. Respectively against and together
Es ist "Zusammen" verdammt noch mal ! Of is 't Nochmal aanmekaar geschreeft?
In 4:01, why din't you name it as an alkene?
Kudus!! Great video
I really wanted the same video while I was taking my University organic chem exam.
how do you know the 1,2-shift will happen or happens?
Hi! I hope everyone has an amazing day!💞
I make vidz
It’s the way my teacher was JUST teaching this topic today....
This was amazing!
thanks crash course team fo helping us in here....🙋🙏😇
Where is the difference to the Wagner Meerwein Shift ?
because your explaination is very awesome
At this point, it feels like I am watching a sci-fi movie with many futuristic terms
3:59 is it supposed to be (Z)-4-bromo-3-ethylpent-3-en-1-yne?
there are a triple bond so using the longest chain, which is hexane. However, I'm confused as why is bromo 5 not 6?
@@ghaithballich5952 oh i got it, thx. the chain starts from the "yellow no 1" to the "white no 2" (from upper right to the lower left). Bromo located on Carbon no 5 that double bound with Carbon no 4. In this case, Carbon no 4 attached with ethyl group. So that it is 5-Bromo.
7:13 that Pizzamas shirt of John lol
Thanks ma'am 😇😇😇😇🌸🌸🌸🌸
The way I remember E isomers is that they are enemies, so of course they are on opposite sides.
Great mnemonic to remember this!
Excellent!
This helped me sooo much
thank you!!!!

IIT JEE
I hope you can update the next episode quickly
Interesting.
Isoprene rocks.
Wohoo thanks for this
Where are the dashes and wedges :’))
Simple mechanics and complex Mechanics Theory
Excelent!
Is this CC nomenclature grammar rules?
I read that you have to have IDENTICAL groups on each side of the double bond for it to be cis or trans, but that's not what you are showing here.
I’m early!!! Yayy😍
WE NEED MATERIALS SCIENCE COURSE
❤️
wait you ate this
With English subtitle please🙏
Could you do videos on animal science???
Haha, I knew about (Z) for zussamen but for (E) I thought it was Eigen as in unique because they were in a unique place
00:07:25 PIZZAMASSSSSSSSSSS
heck yes! :D
I’m early! If only I got a heart
lol thank you!
First?
no
You lost me with the shift stuff ! I hate chemistry
