Chemistry Question from JEE Main 2023 · 11 April, Shift 1

Reaction scheme showing an alkyl-substituted cyclohexanone treated with KMnO4 to give A, then NH2NH2 and KOH followed by H3O+ to give B as major product.

(R = alkyl)

'A' and 'B' in the above reactions are:

  • A
    Option showing A as a carboxylic acid chain and B as a dihydrazide-like product with terminal carbonyl hydrazine groups.
  • B
    Option showing A as a chain containing carboxylic acid and aldehyde groups, and B as the corresponding alkyl-substituted carboxylic acid.
  • C
    Option showing A as an alkyl-substituted keto-acid and B as the corresponding alkyl-substituted monocarboxylic acid after carbonyl reduction.
  • D
    Option showing A as an alkyl-substituted keto-aldehyde and B as the corresponding alkyl chain ending in methyl group.
