TestHub · Accepted Answer

The species with intramolecular hydrogen bonding are (a), (b), and (d).

(a) Salicylic acid has -OH and -COOH groups ortho to each other.

(b) Chloral hydrate has two -OH groups on the same carbon, stabilized by intramolecular H-bonding with chlorine.

(d) o-Nitrophenol has -OH and -NO₂ groups ortho to each other.

The correct answer should be 3.
