Question
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
Solution
B.
o–Nitrophenol shows Intramolecular H–bonding
There is intramolecular H-bonding in o-nitrophenol and thus solubility in water is decreased.
