Answer 2

Acetone reacts with the Grignard reagent to form t-butyl alcohol.

• The formula of the methyl Grignard reagent is $CH_3MgBr$.
• The methyl Grignard reagent undergoes nucleophilic addition reaction to carbonyl compound acetone to form t-butyl alcohol.
• In this reaction, methyl anion attacks the acetone followed by protonation to form t-butyl alcohol.
• The reaction is as follows-
• $CH_3-CO-CH_3+CH_3MgBr\rightarrow (CH_3)_3OH$.
