Q. If (dl) or ( ) 2-methyl butanoic acid were esterified by reaction with (dl) or ( ) 2-butanol, how many optically active compounds would be present in the final equilibrium reaction mixture?

Alcohols Phenols and Ethers Report Error

A

B

C

D

Solution:

-methyl butanoic acid and -butanol

Ester consists of two stereocentres. Chiral center during whole reaction are not effected, that's why all esters are optical active.
