Priority in Isomers

Postby Yinhan_Liu_1D » Sun Mar 05, 2017 6:09 pm

On the organic textbook, page 156, when it is discussing the S/R isomers, it mentions the priority in drawing the structure: Nu> CH2CH3>CH3>H.

Where does this come from? Is the priority according to the number of carbon?

I would appreciate your help.

Here is a list of functional groups and their priorities when coming to naming: ... enclature/
