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

Answer (2) is correctOrtho nitrophenol forms intramolecular hydrogen bonding therefore the active hydrogen is not available for making hydrogen bond with water molecule hence less soluble in water.

Ortho -nitrophenol is less soluble in water than p-and m-nitrophenols because. o-nitrophenol is more volatile stema than those of the and p-isomers. Solution : There is intramolecular H-bonding in o-nitrophenol and thus solubility in water is decreased.
