Question

Which is the best reaction for preparation of t-butyl ethyl ether ?

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Williamson Ether Reactions involve an alkoxide that reacts with a primary haloalkane to produce ether. Alkoxides consist of the conjugate base of an alcohol and are comprised of an R group bonded to an oxygen atom. They are often written as $R{O}^{–}$, where R is the organic substituent.
Only option (b) has primary alkylhalide thus it is used in preparation of t-butyl ethyl ether.
