Grade 12th passOrganic Chemistry

Ortho-Nitrophenol is less soluble in water than p– and m– Nitrophenols because:
(1) Melting point of o–Nitrophenol is lower than those of m– and p– isomers
(2) o–Nitrophenol is more volatile in steam than those of m– and p– isomers
(3) o–Nitrophenol shows Intramolecular H–bonding
(4) o–Nitrophenol shows Intermolecular H–bonding

Answer ::

Intramolecular H-bonding is present in o-nitrophenol. So solubility in water is decreased.
Hence option (3) is the answer.
