What is the product of the reaction between and concentrated ?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: A —
Solution
- Benzaldehyde has no alpha-hydrogens, so it cannot undergo aldol condensation.
- In the presence of concentrated , it undergoes a disproportionation reaction known as the Cannizzaro reaction.
- One molecule of benzaldehyde is oxidized to sodium benzoate.
- Another molecule of benzaldehyde is reduced to benzyl alcohol.
- Hence the answer is (A).
