The compound A, C ₈ H ₈ O ₂ reacts with acetophenone to form a single product via cross-Aldol condensation. The compound A on reaction with conc. NaOH forms a substituted benzyl alcohol as one of the two products. The compound A is :

Options

  1. A2-hydroxy acetophenone
  2. B4-methyl benzoic acid
  3. C4-methoxy benzaldehyde
  4. D4-hydroxy benzaldehyde

Correct answer

C. 4-methoxy benzaldehyde

Step-by-step solution

(On cross aldol reaction, a single structure is obtained but it can show geometrical isomerism).
