Which of the products is formed when acetone is reacted with barium hydroxide solution?

A
Correct Answer
B
C
D

Solution

The acetone is a Ketone with three carbons, a carbonyl group between two methyl groups. Its the smallest ketone. When reacting with barium hydroxide solution, the acetone undergoes aldol condensation.

The electrophilic centre of the carbonyl group of acetone is attacked by beta hydrogen of other acetone.

This opens up the carbon-oxygen double bond of the 1st acetone which forms a 3° alcohol and the hydrogen that attacks the electrophilic centre of the acetone is taken up by the oxygen to form alcohol. This gives Diacetone alcohol.
