Type: MCQ-conceptual-Medium-Class 12

Compound P(C₆H₅O) gives a red orange precipitate with 2,⁴⁻DNP reagent and it does not reduce Fehling’s reagent. On drastic oxidation with chromic acid, P gives an aromatic product Q that produces effervescence on treating with aq. NaHCO₃. Compounds P and Q, respectively, are:

Correct Answer

Option A

Detailed Explanation

Benzaldehyde gives a positive 2,⁴⁻DNP test and does not reduce Fehling's solution. Upon oxidation, it forms benzoic acid, which reacts with NaHCO₃ to produce effervescence due to CO₂ release.
