Question

When acetone reacts with dilute aqueous solution of $Ba(OH{)}_2$, the product obtained is called

• A. crotonaldehyde
• B. diacetone alcohol
• C. Phorone
• D. Acetophenone

Answer 1

The correct option is B

diacetone alcohol

Self-aldol reaction of acetone yields 4-hydroxy 4-methylpentan-2-one - which is also known as diacetone alcohol. Since only a dilute base is used, the dehydration is not favoured.
