Phenyl magnesium bromide reacts with methanol to give
  1. (A)a mixture of anisole and
  2. (B)a mixture of benzene and ✓ Correct
  3. (C)a mixture of toluene and
  4. (D)a mixture of phenol and

Answer: (B)

Solution

Phenylmagnesium bromide is a Grignard reagent, and the carbon bonded to magnesium is strongly basic. Methanol is a protic solvent, so its proton is handed to the phenyl carbanion, which leaves as benzene, , while the methoxide pairs with magnesium. The products are therefore benzene together with .
