Question

Identify the major product (Y) from the following reaction.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Grignard + CO2} gives carboxylic acid, which on LiAlH4} reduction gives primary alcohol.

Answer 1

The Correct Option is C

Step 1: Ph–Cl + Mg in dry ether → Ph–MgCl (Grignard reagent)
Step 2: Ph–MgCl + CO2} → Ph–COOMgCl → H3}O\textsuperscript{+} → Benzoic acid (intermediate X)
Step 3: Benzoic acid + LiAlH4} → Benzyl alcohol (reduction of –COOH to –CH2}OH)
