JEE Main · 2024 · 05 Apr 2024 · Shift 1 · Aldehydes Ketones and Carboxylic Acids

Identify ' A ' in the following reaction :

(A)(see structure)
(B)(see structure)
✓ Correct
(C)(see structure)
(D)(see structure)

Answer: (B)

Solution

Treatment of the ketone with hydrazine (

N_{2} H_{4}

) followed by heating with a base in a high-boiling solvent (ethylene glycol/KOH) is the Wolff-Kishner reduction, which converts the carbonyl group

C = O

into a methylene

C H_{2}

. The product 'A' is the corresponding hydrocarbon, structure (B).
