Match List-I with List-II.

Choose the correct answer from the options given below:

  1. A

    A-II, B-III, C-IV, D-I

  2. B

    A-IV, B-III, C-I, D-II

  3. C

    A-IV, B-I, C-II, D-III

  4. D

    A-II, B-IV, C-I, D-III

Solution

Match each reagent set with its named reaction:

A. over Pd-BaSO (Lindlar-type poisoned Pd) reduces acyl chlorides to aldehydes — Rosenmund Reduction (II).

B. converts a nitrile to an aldehyde via an imine intermediate — Stephen Reaction (IV).

C. in oxidises toluene-type methyl groups to aldehydes via a chromyl complex — Etard Reaction (I).

D. with anhydrous formylates arenes — Gatterman–Koch Reaction (III).

So A-II, B-IV, C-I, D-III.
