Q. 27

Note : A statement of assertion followed by a statement of reason is given. Choose the correct option out of the options given below each equation.

Assertion : p-nitrophenol is more acidic than phenol.

Reason : Nitro group helps in the stabilisation of the phenoxide ion by dispersal of negative charge due to resonance.

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.

B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.

C. Assertion is correct statement but reason is wrong statement.

D. Assertion and reason both are incorrect statements.

E. Assertion is wrong statement but reason is correct statement.

Answer :

Nitro group is an electron withdrawing group and its presence on the ortho and para position of the ring results in the decrease of the electron density of the OH bond due to which the H+ ion can be released easily. The nitro group stabilizes the phenoxide ion by dispersal of negative charge due to resonance. But in case of phenol no such group is present so p-nitrophenol is more acidic than phenol.
