The smallest ketone and its next homologue are reacted with `H_(2)NOH` to form oxime

A

all oximers are optically active

B

three differe oximers are formed

C

two oximers are optially active

D

two different oximers are formed

Text Solution

Verified by Experts

The correct Answer is:
B
Symmertical carbony`1` compounds form oximers which cannot exists as cis-trans isomers while unsymmetrical carbony`1` compounds reat with `H_(2)NOH` to give two oximes (syn and anti).
The simplest ketone, acetone, is symmeterical and froms only one oxime:

The next higher homologue, butan`-2-`one, is unsymmetrical and thus forms two oximes (syn and anti):
