Which among the following phenols has highest melting point?

(A)o-Nitrophenol
(B)p-NitrophenolCorrect
(C)p-Cresol
(D)Phenol

Answer: (B)

Solution

Melting point depends on the strength of intermolecular forces. p-Nitrophenol forms strong intermolecular hydrogen bonds (associated molecules), and its symmetrical shape packs well, so it melts highest (about 114 degrees C). In o-nitrophenol the
