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

Options

A. o-Nitrophenol is more steam volatile than its m- and p-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

B

Explanation

Compounds involved in chelation become non-polar. Consequently, such compounds are soluble in non-polar solvents like ether, benzene etc. and are only sparingly soluble in water whereas meta and para isomers are more soluble in water & less soluble in non-polar solvents.
