Question

The product formed in an aldol reaction is: (A) a β - hydroxy aldehyde or ketone (B) an α - hydroxy aldehyde or ketone (C) an α ,β - unsaturated ester (D) a β - hydroxy acid

Tardigrade Admin · Accepted Answer

In an aldol condensation reaction, a few steps take place in this reaction:
Step 1: Acid-base reaction takes place in between base and alpha hydrogen of ethanal and carbanion is formed.
Step 2: In this step formed carbanion behaves as nucleophile and attack carbonyl compound carbon (ethanal).
Step 3: Water gives proton to form a

hydroxy aldehyde or ketone and release hydroxide ion by following heating effect in which alkene is formed as shown below:
