Salicylaldehyde

Vedclass · Answer

(B) Intramolecular hydrogen bonding occurs when a stable five-membered or six-membered ring is formed within the molecule.Benzoic acid,benzaldehyde,and phenol do not possess the necessary structural arrangement to form such rings,and thus they cannot form intramolecular hydrogen bonds.In the case of salicylaldehyde,the hydroxyl group $(-OH)$ is ortho to the aldehyde group $(-CHO)$. This proximity allows the hydrogen atom of the hydroxyl group to form a hydrogen bond with the oxygen atom of the carbonyl group,resulting in a stable six-membered ring as shown below:(Image: $231309-$s)
