In Williamson synthesis if tertiary alkyl halide is used than

Answer»

ether is obtained in good yield
ether is obtained in good yield
alkene is the only reaction product
a mixture of alkene as a MAJOR product and ether as a minor product forms

Solution :lf a TERTIARY alkyl halide is used, an alkene is the only reaction product and no ether is formed. For example, the reaction of `CH_(3)Ona` with `(CH_(3))_(3)C-Br` 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.
