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

Options

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

Answer

A

Explanation

In o-nitrophenol, -OH & `-NO_(2)` groups are situated at two adjacent carbon atoms of the ring and inolved in intramolecular H-bonding. So, o-nitrophenol is less soluble in water than p- and m-nitrophenol.
