In a bond line structure a tetrahedral atom is drawn having 2 bonds in the plane, 1 wedge, and 1 dash. So see which bond isn't drawn yet, and that is the type the unseen hydrogen atom must have. Hope this helps!

Hi, if you are working backwards and are given the name first with an R and S then asked to draw the skeletal structure. How do you know which elements around the chiral carbon get the wedge the line and the dash? For example, if it was a hydrogen a bromine a methyl and an ethyl, which of the four gets the wedge, dash or line. Many thanks for your time

Hi Chad! I have a question. So at 18:29, for the second example we are looking at, is it *necessary* to go label all of the C's and H's? Since we know the C on the right has a longer carbon chain, is it okay to just assume that that would be ranked above the one on the left?

Hi Rohit! The carbon under the oxygen is sp2 hybridized and trigonal planar. As such it is only bonded to 3 atoms. Only sp3 hybridized, tetrahedral atoms have a chance of being chiral centers. Hope this helps!

So, when you say 4 different groups- CH2 and CH3 are different, even though they are both carbon? (I would say they are different) If so, does this mean a chiral center cannot be double bonded?
@ChadsPrep
2 жыл бұрын
Hi again Vladimyr! Yes, 4 different groups need not mean four different atoms. A carbon bonded to methyl group, an ethyl group, a propyl group, and a butyl group would be a chiral center. And a chiral center must be tetrahedral (and therefore sp3 hybridized) so a carbon with a double bond could not be a chiral center. Hope this helps!

At 16:15 why is it that you count SH as S H H instead of H H as it should be bonded. When you look at the substituent groups and what it's bonded to, you write what it's bonded to and not the group itself. Say for the first example you say O O O instead of C O O, not counting the carbon? My big question is why you are comparing S to O's when you should automatically declare S as first priority automatically as it should be compared to carbons, not the oxygen it's attached to.

@@ChadsPrep It is when you're assigning R and S configurations. For the molecule on the very left, you are comparing S with O. However, S is directly connected to the chiral carbon while the O is connected to the carbon CONNECTED to the chiral carbon.

Ah got you - it is for the previous example around the 13:00 min mark correct? The chiral carbon is the one marked with a star, so the CH2(SH) is one group and COOH is another, both S and O are one carbon away from that starred chiral carbon if you go back and check

pls don't jump my comment I really need help for my assignment. my question is if we got two chiral and they have the same designation that means both r or s how can we rename it? 2.if we are asked to put the relation after we assign r or s and if we ger 2R,3R and the same for the second one what is the answer us it diastereomers or enatiometric? pls give me answer I am your subscriber and follower
@ChadsPrep
11 ай бұрын
1. Whether both chiral centers have the some configuration or different configurations, you would still list the designation with the carbon number at the beginning of the name [ex. (2R, 3R)- or (2S, 3S)- or (2R, 3S) or (2S, 3R)]. 2. Also, if the two structures your are comparing have the same bond connectivity, then they are either identical or some form of stereoisomer. If their chiral centers are in the same configurations, then they are identical. If all their chiral centers are in the exact opposite configurations, then they are enantiomers. If some of their chiral centers are in the same configuration, and some are in the opposite configuration, then they are diastereomers. I go over this last part in the very next lesson in the playlist 😊
