Which of the following statements is/are correct ?

Answer

A, B

Explanation

The reasonance structure of 2-napthoxide ion (A) is:

(A) is an ambident nucleophile and a better nucleophile than `(A_(1))` because negative charge is on more EN oxygen atom. In the presence of polar non-protic solvent (DMF, dimethyl formamide), O-alkylation is favoured to give product II (C ). In the pressence of protic solvent, hydrogen bonding with the O atom occurs, thus reducing the nuclehilicity of oxygen. Therefore, C-alkylation is favoured to give product I (B).
