Vedclass · Answer

(D) The synthesis of crotonaldehyde from acetaldehyde occurs in two steps: $1$. Aldol condensation of two molecules of acetaldehyde $(CH_3CHO)$ in the presence of dilute $NaOH$ to form $3-$hydroxybutanal (aldol). This step is a nucleophilic addition reaction. $2$. Dehydration (elimination of water) of $3-$hydroxybutanal upon heating to form crotonaldehyde $(CH_3CH=CHCHO)$. Since the overall process involves both nucleophilic addition and elimination,it is classified as a nucleophilic addition-elimination reaction.

The synthesis of crotonaldehyde from acetaldehyde is an example of ....... reaction.
