I think confusion with the last example comes from not being sure how to deal with a ring. This would be one way to go about it: 1) Start at a particular carbon on a ring and follow a path (i.e. clockwise) all the way around that returns you to your starting point. 2) Begin at the same carbon and follow a path all the way around in the opposite direction (i.e. counterclockwise). 3) If the paths in both directions were the same, your starting carbon would NOT be a chiral center because the ring itself would be symmetrical (so therefore there aren't 4 different groups attached). If the paths differed at some point (for example, say that the ring has an OH group and you encounter that group sooner as you move clockwise around the ring than if you moved counterclockwise) then your starting carbon would be a chiral center. It's hard to explain it without a demonstration, but hopefully that helps anyone that was also confused!

i dont get how when i teach somebody shit ill explain every detail you need to know but when a professional professor teaches they dont explain important crucial shit to solve problems. Like i literally had no idea there was an invisible hydrogen atom which is why i kept thinking how is there four groups when i only see three and are given three. its not that hard for a teacher to mention something like that but they still seem to fail to do it. this dude is honestly my main professor this semester its sad

Thanks for your video. I just have a question. Can molecules with benzene ring in them have chiral centres in the benzene ring? Like at the point where there is a branch coming off the ring?

My textbook did such a crap job explaining this. I'm sitting there seeing an indicated chiral center that's attached to a hydrogen, a ch2 a ch2 and an hydroxide trying to figure out how ch2 and ch2 are different groups. It failed to explain that everything else attached to each carbon constitutes as a group. Thank you so much!!!

For the second to last example you did in this video (one with cyclopentane, methyl, fluorine, and OH), how can you tell that the carbon in the cyclopentane attached to the OH has two of the same things around it? Is it because there are two carbons (from the cyclopentane) on one side of the carbon attached to -OH and then two other carbons (from the same cyclopentane) on the other side of the carbon attached to -OH?

@Majesticman47

Not sure if you still need an answer but the reason is that, if you were to follow both sides of the ring at the same time, you’d get through 2 and a half carbons on each side (meeting in the middle of the bond). Although he drew the lines to be different lengths, they each represent a bond of equal length. So, although it looks like there’s 3 bonds on one side and 2 bonds on the other of the pentagon, it’s actually 2.5 on each side.

That is for the chiral center connected to nh2. The one on the left and the right when looked at separately are chiral centers because they have 4 different groups attached to the carbon: one is the long chain, another is the hydrogen, the oh, and the ch3 group. The left and the right chiral centers are the same in this regard but are not associated with each other.

Thank you!

@fyroboi2053

4 ай бұрын

We don't mention hydrogen when we write bond line structure of any organic compound but sometimes people overlook this "hydrogen atom" so it's named invisible as a joke it doesn't mean hydrogen atom doesn't exist we just don't show it

I owe you my degree man I swear

Would of loved to hear the explication of the last example but the video cuts off…

Why is there an invisible hydrogen in every chiral center?

@anjleesharma1599

3 жыл бұрын

@Giorno Giovanna Actually, we won't call that as an invisible hydrogen. It's there because carbon always form 4 bonds and the structure that we're drawing is called bond line structure. It's the main purpose of drawing the structure as bond line so that we can reduce it and even after that we are able to represent the whole compound. That's why, hydrogen is present there so that we can satisfy the valency of carbon(having the tendency to form 4 bonds). I hope, this will help :)
