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

Options

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

Answer

B

Explanation

Due to the presence of intramolecular hydrogen bonding, molecules of o-nitrophenol are not involved in any hydrogen bonding with the molecules of water whereas those of p-nitrophenol and m-nitrophenol exibit hydrogen bonding with water molecules.Therefore, o-nitrophenol is less soluble in water as compared to p- and m-isomers.
