Question

This equation shows the reaction of trans-2,3-dimethyloxirane with hydrogen chloride to form 3-chloro-2-butanol.

how many total stereoisomer are possible for 3-Chloro-2-butanol?
Given that opening of the epoxide ring in this reaction is stereoselective, provide the names of the only two isomeric products using IUPAC guidelines.
Product one: _______ 3-chloro-2-butanol
Product two: _______3-chloro-2-butanol

Answer 1

Product one: (2S, 3R)-3-chloro-2-butanol

Product two: (3S, 2R)-3-chloro-2-butanol

Step-by-step explanation:

The IUPAC name of the products following IUPAC guidelines are :

Product one: (2S, 3R)-3-chloro-2-butanol

Product two: (3S, 2R)-3-chloro-2-butanol
