    In which of the following reactions the product obtained is t-butyl methyl ether?

    A)  \[\left( \frac{\Delta {{x}_{A}}}{\Delta {{x}_{B}}} \right)\]

    B)  \[2\]

    C)  \[0.25\]

    D)  \[4\]

    Correct Answer: C

    Solution :

    t-butyl methyl ether is a mixed ether and for the preparation of mixed ethers in high yield the essential condition is the use of primary alkyl halide. Thus, \[C{{H}_{3}}Br+N{{a}^{+}}{{O}^{-}}-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}}\xrightarrow{{}}\] This reaction is williamsons synthesis.
