Answer: Benzyl alcohol and sodium benzoate.
- A Benzyl alcohol and sodium benzoate
- B Benzoic acid and acetaldehyde
- C Benzene and CO<sub>2</sub>
- D Toluene
Correct answer: A. Benzyl alcohol and sodium benzoate
Explanation: One mole of benzaldehyde is oxidised to sodium benzoate and another is reduced to benzyl alcohol.
Curved arrows show the nucleophile attacking the carbonyl carbon while the C=O pi electrons move onto oxygen, giving a tetrahedral alkoxide intermediate.
Concept context
Aldehydes, ketones, carboxylic acids, and their derivatives (esters, amides, acid chlorides). Key reactions include nucleophilic addition, Aldol condensation, Cannizzaro, and Claisen. Very heavily tested in JEE and NEET.
