JEE Main Chemistry question

To prepare an ether by Williamson's synthesis, the reactants needed are

(A)Ethyl alcohol and tert butyl alcohol
(B)Sodium ethoxide and ethyl tert butyl bromide
(C)Sodium tertiary butoxide and ethyl bromideCorrect
(D)Sodium ethoxide and sodium tert butoxide

Answer: (C)

Solution

Williamson's synthesis requires one alkoxide (nucleophile) and one alkyl halide (electrophile); for best yield with a tertiary group involved, the tertiary alkoxide (sodium tert-butoxide) should be
