Question 63

Match List - I with List - II.

Choose the correct answer from the options given below:

Solution

Rosenmund Reduction: Converts acyl chlorides to aldehydes using a poisoned catalyst. Ex. C₆H₅COCl + H₂ → C₆H₅CHO

Stephen Reaction: Reduces nitriles to imines (which hydrolyze to aldehydes) using stannous chloride. Ex. C₆H₅CN → C₆H₅CHO

Etard Reaction: Uses chromyl chloride to oxidize a methyl group on an aromatic ring to an aldehyde. Ex. C₆H₅CH₃ → C₆H₅CHO

Gattermann-Koch Reaction: Formylates benzene or its derivatives using carbon monoxide and hydrochloric acid. Ex. C₆H₆ + CO + HCl → C₆H₅CHO
