Reaction between benzaldehyde and acetophenone in presence of dilute NaOH is known as

Options

  1. ACannizzaro’s reaction
  2. BCross Cannizzaro’s reaction
  3. CCross Aldol condensation
  4. DAldol condensation

Correct answer

C. Cross Aldol condensation

Step-by-step solution

Cross aldol condensation reaction: A few steps take place in this reaction Step 1: Acid-base reaction occurs between base and alpha hydrogen of acetophenone, and carbanion is formed. Step 2: In this step, formed carbanion behaves as a nucleophile and attacks carbonyl compound (benzaldehyde) carbon to form beta-hydroxy carbonyl compound. Step 3: α , β -unsaturated carbonyl compound is formed as a product after heating.
