Identify products [P\(_1\)] and [P\(_2\)] formed when Benzonitrile undergoes the following reactions.

- A [P\(_1\)] Phenol and [P\(_2\)] Sodium benzoate
- B [P\(_1\)] \(\alpha\)–Hydroxy phenylacetic acid and [P\(_2\)] Benzyl alcohol
- C [P\(_1\)] Benzoyl chloride and [P\(_2\)] Acetophenone
- D [P\(_1\)] Acetophenone and [P\(_2\)] Benzoic acid
Answer & Solution
Correct Answer
(B) [P\(_1\)] \(\alpha\)–Hydroxy phenylacetic acid and [P\(_2\)] Benzyl alcohol
Step-by-step Solution
Detailed explanation
1. Formation of [X]: Benzonitrile (\(C_6H_5CN\)) undergoes Stephen reduction when treated with \(SnCl_2/HCl\) in ether, forming an imine intermediate. Subsequent acid hydrolysis (\(H_3O^+\)) yields benzaldehyde (\(C_6H_5CHO\)). Thus, [X] is benzaldehyde. 2. Formation of…
