Question

Acetophenone can be obtained by the reaction of $PhMgBr$ and :

• A. Ethane nitrile
• B. Ethanamide
• C. Ethanoyl chloride
• D. Methanamide

Answer 1

Answer: (A), (B)

The correct options are
A Ethane nitrile
B Ethanamide

Acetophenone can be obtained by the reaction of phenyl magnesium bromide ($PhMgBr$ - a Grignard reagent) and either (A) Ethane nitrile or (B) Ethanamide.
On the other hand, the reaction of $PhMgBr$ with Ethanoyl chloride will give a tertiary alcohol and the reaction of $PhMgBr$ with Methanamide will give benzaldehyde.
