Question

In Williamson synthesis if tertiary alkyl halide is used than (A) ether is obtained in good yield (B) ether is obtained in poor yield (C) alkene is the only reaction pro (D) a mixture of alkene as a major product and ether as a minor product forms.

Tardigrade Admin · Accepted Answer

If a tertiary alkyl halide is used, an alkene is the only reaction product and no ether is formed. For example, the reaction of

C H_{3} ON a

with

(C H_{3}) 3 C - B r

gives exclusively

2

-methylpropene.
It is because alkoxides are not only nucleophiles but strong bases as well. They react with alkyl halides leading to elimination reactions.
