Ma'am! You have made a mistake while finding the total number of chiral centers in the last example. You just mentioned the four chiral centers. In a fact, there are the five chiral centers in the last example. Hope, you will reconsider it. Thank you for a nice lecture. ❣

Am I supposed to focus on every substituent attached to the carbon in question? For example, in the first chiral group with the chlorine, I didn't realize I was supposed to be taking the CH2 and CL in to account. IS this correct?

@RoxiHulet 20 күн бұрын

Very good question! Yes, you are correct. When you are trying to decide if a carbon is chiral, you will always look at the whole entire collection of atoms coming off each of its four bonds.

Hi! Can we draw the conclusion that all carbon atoms that are part of a ring, have 4 single bonds, and have only one H are chiral carbons?

@RoxiHulet 2 жыл бұрын

No, you can’t. If two of those non-H single bonds are to identical groups (such as, two methyl groups) the carbon would be achiral.

Mam u said sp2 hybridised carbon is never chiral okk, But what About a 2 degree nitrogen which has diffrent carbon chains on both sides and 1 loan pair. So is the nitrogen chiral or not? Its very confusing as the nitrogen is sp2 hybridised as well.

@RoxiHulet 3 жыл бұрын

That nitrogen is actually sp3 hybridized. :) sp3 hybrid atoms have 4 total bonds / lone pairs. A secondary nitrogen has 3 bonds and 1 lone pair.

@@Utpal-fj4hk oh, I understand. We use different classification systems. The system I use is that a tertiary nitrogen or carbon has 3 bonds to C chains and one lone pair or hydrogen If you only have 2 bonds to carbon and one lone pair, the atom cannot be chiral. In order to be chiral you must have a total of 4 things (bonds or lone pairs) around the atom.

I am a little confused with the last example... the 2nd and 3rd substituents you said they both eventually have an immediate connection to a benzene ring so wouldn't that be achiral because they're not unique? Can you explain please

They have different paths to the benzene ring, which makes them unique.
