Ortho-nitrophenol is less soluble in water than p- and m-nitrophenols because
A
o-nitrophenol shows intramolecular H-bonding
B
o-nitrophenol shows intermolecular H-bonding
C
Melting point of o-nitrophenol is lower than those of m- and p-isomers
D
o-nitrophenol is more volatile in steam than those of m- and p-isomers
Answer
o-nitrophenol shows intramolecular H-bonding
Explanation
Solution
o-Nitrophenol is stable due to intramolecular hydrogen bonding.
It is difficult to break the H-bonding when dissolved in water thus less soluble.
