Complete the following reaction

Options

A. `C_(6)H_(5)OC_(2)H_(5)`
B. `C_(2)H_(5)OC_(2)H_(5)`
C. `C_(6)H_(5)OC_(6)H_(5)`
D. `C_(6)H_(5)I`.

Answer

B

Explanation

`C_(6)H_(5)O^(Ɵ)` ion formed by the abstraction of `H^(+)` from phenol by `C_(2)H_(5)O^(Ɵ)` ion is expected to attack `C_(2)H_(5)-I`. But as a weaker nucleophile as compared to `C_(2)H_(5)O^(Ɵ)` ion due to the presence of electron withdrawing `C_(6)H_(5)` group, it does not attack. Rather `C_(2)H_(5)O^(Ɵ)` ion attacks `C_(2)H_(5)-I` to form diethyl ether.
`C_(2)H_(5)O^(Ɵ)+C_(2)H_(5)-I rarr C_(2)H_(5)-O-C_(2)H_(5)+I^(-)`
