MHT CET Chemistry question

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

(A)o-nitrophenol is more steam volatile than those of m- and p-isomers
(B)o-nitrophenol shows intramolecular H-bondingCorrect
(C)o-nitrophenol shows intermolecular H-bonding
(D)melting point of o-nitrophenol is lower than those of m- and p-isomers

Answer: (B)

Solution

In o-nitrophenol the OH group is internally H-bonded to the adjacent , so it cannot H-bond with water and is less soluble, while m- and p-isomers form
