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. ❣

Thank you for this, you deserve all the awards. Very clear and helpful.

This was so helpful when the book, other videos, and the teacher couldn’t explain to me what parts of the molecule I’m supposed to be looking at when determining the chirality center. Thank you so much!!!

Thank you. But what about the carbon atom attached to the OH group in the sixth example.

Fantastic quick breakdown with good variety of examples.

Well explained. The limonene example is why I came here. There can also be non-carbon chiral centres though.

last structure has 5 chiral center

You are the BEST ROXI!!!

Great video! Thank you so much for clarifying.

THANKS A LOT FOR EXPLAINING MAAM❤❤👍👍

The explanation is crystal-clear. I've been confused about the asymmetric carbon problems the whole night ! Thanks god I find this tutorial! Wish I can learn organic chemistry in your class :(

Heyy Roxi , Really appreciate the technique and the way you explain all the topic in such a easy way 👏👏

Wish you were my ochem professor. This video was so helpful and easy to understand. Thank you

Great explanation ma'am✌️✌️

Amazing explanation ❤

omg believe or not this really helped me a lotttt and i mean it! thankyou very much! never thought that organic can be this easy

Excellent!!

You're an angel for explaining this so well. Quick question though: On the last example, why is the carbon bound to the hydroxyl group not a chiral center?

Is chilarity can be checked on atoms like cl , br ??

Thanks

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

12 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.

❤️❤️ thankyou soo mch

Ma'am it's was too helpful for me 😭😭😭😭 thanks 👍🙂🐧♥️

Thank you mam

at 9:13 you have missed the OH group that was attached to the carbon atom, do we want to ignore it nor not ? because it does not have ch2, ch3 and double bond carbon. Could you please explain this to me?

@leenmcheik7862

Жыл бұрын

I was coming here to write the exact same thing! I guess she just forgot about it

For the third one you said that attachment down was a metal group or something but for the second one you said it was CH3 how do we differentiate it

“Methyl” not “metal”. CH3 is called “methyl”.

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

@RoxiHulet

Жыл бұрын

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

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.

In last prganic compound you missed OH group

For different atched group chiral carbon

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.

@@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.

Did you forget the chiral carbon connected to the OH group on the last molecule?

i thought the Carbon having a hydroxyl group in the last example is also chiral.
