Ortho–Nitrophenol is less soluble in water than p– and m– Nitrophenols because :

o–Nitrophenol is more volatile in steam than those of m – and p–isomers

o–Nitrophenol shows Intramolecular H–bonding

o–Nitrophenol shows Intermolecular H–bonding

Melting point of o–Nitrophenol is lower than those of m–and p–isomers.
