Step 1: Understanding the Concept:
The reaction sequence involves the functionalization of benzene into a Grignard reagent, followed by its reaction with a protic source (alcohol).
Step 2: Detailed Explanation:
1. Step 1 ( ): This is electrophilic aromatic substitution (Bromination). Benzene reacts with bromine in the presence of an iron catalyst to form Bromobenzene ( ).
2. Step 2 ( ): The bromobenzene reacts with magnesium metal in dry ether to form the Grignard reagent, Phenylmagnesium bromide ( ).
3. Step 2 ( ): Grignard reagents are extremely strong bases and powerful nucleophiles. When they encounter a molecule with an acidic hydrogen (like the hydrogen in methanol), they immediately undergo an acid-base reaction.
The phenyl group picks up a proton to regenerate Benzene, and the magnesium forms a salt with the methoxide ion.
Step 3: Final Answer:
The final products are benzene and , which corresponds to option (A).
