Question

preparation of

CH3COCH3 to (CH3)2CHOCHO(CH3)2​

Answer 1

Explanation:

Correct option is

B

Phorone

In this reaction, carbonyl oxygen of acetone and two alpha hydrogen atoms of (CH3)2C=CHCOCH3 are lost as a molecule of water to obtain (CH3)2C=CHCOCH=C(CH3)2

The reaction is (CH3)2C=CHCOCH3→(CH3)2CO(CH3)2C=CHCOCH=C(CH3)2+H2O

This reaction occurs in acidic medium and is similar to aldol condensation which occurs in basic medium.

Hence, compound X is phorone.
