Q. Ethers are prepared by the reaction of sodium alkoxides and alkyl halides. Which of the following reagents should be taken to prepare methyl tert-butyl ether?

Alcohols Phenols and Ethers

Solution:

Tertiary halide can involve elimination of $HX$ to give alkene in presence of a base. Hence, a tertiary alkoxide and primary alkyl halide is taken for the reaction.
$CH _{3} Br +\underset{\text { sod. t-butoxide }}{ NaOC\left( CH _{3}\right)_{3}} \longrightarrow \underset{\text { methyl t-butyl ether }}{ CH _{3} O - C \left( CH _{3}\right)_{3}}+ NaBr$
