The aldol condensation of acetaldehyde results in the formation of:
The aldol condensation of acetaldehyde results in the formation of:
The correct option is B CH3−CH(OH)−CH2−CHO
The Aldol addition reaction involves the addition of alpha-carbon of an enolizable aldehyde or ketone to the carbonyl group of another aldehyde or ketone and thus by giving a beta-hydroxy carbonyl compound also known as an aldol (indicating both aldehyde and alcohol groups). The reaction is catalyzed more commonly by a base or sometimes by an acid.
If the beta-hydroxy carbonyl compound containing a α-hydrogen undergoes subsequent dehydration to yield an alpha, beta-unsaturated carbonyl compound, the entire process is also called as Aldol condensation. The dehydration step is possible under the aldol reaction conditions or mostly carried out by heating in presence of an acid or sometimes during acidic work up.
