Question

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

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

Answer 1

Answer: (B)

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