MHT CET 2025 Chemistry question

Which from following statements is NOT true for phenol?

(A)Phenols are polar molecules.
(B)Pure phenol is odourless, nontoxic, high melting solid.Correct
(C)Boiling points of phenols increases with increase in molecular mass.
(D)Phenols show appreciable solubility in water.

Answer: (B)

Solution

(A) is true: the polar C-O and O-H bonds make phenols polar. (B) is false: pure phenol (carbolic acid) is a colourless, hygroscopic, low-melting solid (m.p. about 314 K, 41 degrees C) with a characteristic medicinal (carbolic) smell, and it is toxic and corrosive to skin.
