This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. It shows you how to identify the chirality centers or carbon atoms with 4 different groups as well as determining the number of stereoisomers using the formula 2^n where n is the number of stereocenters or asymmetric carbon atoms. This video also helps you to identify a pair of meso compounds which are identical to each other and a possess an internal plane of symmetry. It also discusses how to find a pair of enantiomers which are non-superimposable mirror images of each other such as your left hand and your right hand. Enantiomers lack an internal plane of symmetry.

@MrYahya0101 3 года назад

So for carbon to be a chiral center, it must have 4 different groups attached to it AND it must NOT have a plane of symmetry?

@chrisesca9927 2 года назад

Yes, but keep in mind, if it has 4 different groups attached then that automatically means it doesn't have a plane of symmetry

@SpyderRacing Год назад

Confused a bit at 8:17, you say that it cannot be divided as a mirror image but the way you drew it can actually be divided. If you lay down the molecule and cut it along it's middle axis like a sandwich you could split it. I think once you add in the H going away from or into the paper then you can on longer divide it in half. I think the OH group in that drawing should be coming out or going into the page to account for the implied hydrogen.

@zsib2085 Год назад

????? there's not another OH so how can we draw a line of symmetry anywhere lmao

@SpyderRacing Год назад

@@zsib2085 You can draw a line of symmetry down the middle of 1 molecule and have 2 equal halves. You don't need 2 OH's to have symmetry.

@th3cupcakequeen 5 лет назад

shouldn't the two molecules at 3:38 be identical?

@Mehk 5 лет назад

No because the bromine are on opposite planes. Look at the bromine bonds. If they were identical molecules they would both have either wedge bonds or dashed bonds.
