Ortho -nitrophenol is less soluble in wa...

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

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.

Text Solution

Verified by Experts

The correct Answer is:
B
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.
