Question

Ortho-nitrophenol is less soluble in water than p- and m-nitrophenols because

• A. o-nitrophenol is more steam volatile than m- andp-isomers
• B. o-nitrophenol shows intramolecular H-bonding
• C. o-nitrophenol shows intermolecular H-bonding
• D. Melting point of o-nitrophenol is lower than those of m-and p-isomers

Answer 1

The correct option is B

o-nitrophenol shows intramolecular H-bonding

There is intramolecular H-bonding in o-nitrophenol and thus solubility in water is decreased.
