To be fair fatty acids does have their own respective trivial names according to the long of the chain, like palmitic and stearic which is not telling you much too but it's easier to remember rather than remembering each number like C-20 is icosanoic and as she said despite all the effort, still many people use trivial name like palmitic acid for fatty acid with C-16 and stearic acid for C-18 😂😂😂
Drake Smith yeahh they do, usually the common ones do. And for other nomenclature also I think it's possible just using lipid number to identify the lipid, but that's just another thing specific to lipid. Still IUPAC nomenclature is the most general one. 😃😃
But why would you 'no Bromo'? Mount Bromo is an active volcano in East Java, Indonesia. I personally wouldn't mess with it 2,329 meters of lava spewing chunck of rock. No flowmo tho

This series came just in time for me to teach organic chemistry for my Chem 12 class. Will definitely be attaching this as a resource to their upcoming assignments.
This is perfect timing for this series to come out because I’m finishing my 2nd year in college as a premed and will be starting to study for the MCAT this summer😊
Classes haven't even started yet and I'm using these to prepare. I'm nervous but it feels good to try, and to actually feel like I'm learning not just drowning in the information
I'm on second semester of university and I'm taking the organic course I'm kind of undertand the themes but this is going to help me even more, I'm about to finish semester so pretty good quality videos and explanations there, love u
You guys are SAVING my life! Could you please make a video about the Isomers (how to find each Isomer, cis and trans isomers etc.) Also, although this is not a Organic Chemistry question, i'd be super glad if you could explain to me the "Chemical Balance". In school, we had some graphs I just didn't understand. Help a girl out please? My exams are in 3 months😫
Even though I am busy with university and all assignments and exams that I have I don't miss watching your updated videos guys😘💕✔ nice episode keep going
Something that wasn't mentioned at the end is that the Carbon atom has its four bonding points in a pyramid shape (like a 4-sided die). That puts any two corners next to each other. So in the diagram of the Cl2C molecule, it doesn't matter where the Cl atoms are in the skeleton (either adjacent or opposite).
If the four substituent groups were different though (example 1-Bromo-1-chloro-1-iodomethane), then the location of atoms in the structure matters because of stereochemistry (YAY?). Check out the R/S (rectus/sinister) configuration for more information. Granted, this Crash Course can never cover that level of detail and still be a *Crash* Course. I do hope they cover a bit of stereoisomerism though.
Awesome job! I never took orgo, but you just made nomenclarure so much more obvious. I’m so glad that I subbed to this channel many years ago and discovered this hidden gem
man chemistry is such an underated science. feel like evrey1 these days is only interested in physics or biology. pretty unsetting considering what a beautiful branch of science it is.

She said "...ethyl group, which is 2 carbons and 6 hydrogens, at carbon 3..." which should have been "...5 hydrogens..." so you may actually have found a mistake but you are mistaken in how you articulate it.
This reminds me of my high school chemistry teacher making us yell out the number preffixes of the root name over and over until we had them memorized. It was kinda fun!
Thankyou for this video The way you explain things is so clean and on point , other lectures give you either too much info at one time so you get lost or they just don't do an efficient job of teaching the mechanics Kudos to you
Welcome to 2020. I'd like to say universities will be gone in a few decades, the truth is too much money is made for the super rich through universities so they'll be around for a while. But as time goes on, they'll be forced to dwindles down to only the courses someone NEEDS to do a profession such a doctor or nurse.
I call a carbonated beverage by it's flavor or brand name (Coke, Pepsi, etc), and use the terms 'drink', 'soft drink', "carbonated beverage" etc when speaking generically. When I was younger and less articulate and careful in word choices I may have used the phrase "soda pop" on occasion, but since my Dad always said 'soft drink', and more often used brand and flavor names, I picked up on that.
I think you might be counting just the bends as carbons, when there is also a carbon on every straight line where another parallel line starts or ends. You don't put a bend in the line at the start of a triple bond because atoms attach to a triple-bonded carbon at 180 degrees unless forced, and the way you draw the structure is supposed to resemble the actual geometry to a decent approximation, so that's why we usually draw triple bonds as continuing the line on which they start. Either that or you're missing the ends of the lines.
Wait, I remember that there's a slightly different way of naming them. For example I thought you could name 3-ethylpent-1-ene this: 3-ethyl-1-pentene is this no longer the case? Or for example But-1-ene as 1-Butene?
I missed my first chemistry lecture in which organic chemistry was introduced and l was like what am l going to do as l was nit understanding a word of anything when l tried to read from my textbook... so honestly this series has been a life saver, I am sure l would have failed this year without it ... 🙏🏻🙏🏻🙏🏻🙏🏻 Ps - l now understand it better than those who attended the lecture
The video is correct. I believe you are mistaking the triple bond as acting like a functional group rather than part of the longest carbon chain. Look at the structure again closely and watch the numbering in the video. It shows that the alkyne contains two carbons and thus is located on the 6th carbon in the chain and the longest chain is 7 or hept. Check 11:03 for the best picture.
More than the other sciences, chemistry always feels like the first part of any course is designed to put you off. I sure hope this gets easier and more interesting (I'm sure it will and I know this stuff is important).
Man, UA-cam should've picked up on all these kinds of videos 7 years ago. 😜 Teaching vids were pretty low-tech back then, even Khan Academy had those growing pains. This makes o-chem interesting. 😂
Question: for dichloromethane, how do you know (or does it not matter, and why) that the chlorines are adjacent to each other rather than opposite each other?
As it happens, it does not matter, but it's a good question because it can matter sometimes. Atoms around carbon aren't aranged in a square but a tetrahedron so all atoms are adjacent and none are opposite another. There are situations in which it does matter whether you draw specific atoms or groups on the left, right, top or bottom of a carbon though, which will undoubtedly come up in a future episode. Maybe you can already think of a molecule like that.
@@Quintinohthree Thanks. I figured that was the case but was struggling to picture it in 3D to satisfy my suspicion. I knew it definitely mattered sometimes (isomers, right?), so I wasn't sure about this one.
Gosh that makes me laugh does days in lab when we tried to use the wrong chemicals in lab 😂😂 and joked about we will be able to make all this awesome things
When I was a kid, my teacher has always told me not to put in my mouth anything I couldn’t read. Then again, Dihydrogen Monoxide doesn’t exactly roll of the tongue either.
