Grignard reagent on reaction with acetone forms — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Acetone is a ketone. A Grignard reagent adds an alkyl group to the carbonyl carbon, giving a tertiary alkoxide, which on hydrolysis forms a tertiary alcohol. Thus acetone with $RMgX$ ultimately gives a tertiary alcohol.
