    t-butyl chloride preferably undergo hydrolysis by.           

    A)  \[{{S}_{N}}1\]mechanism           

    B)  \[{{S}_{N}}2\]mechanism           

    C)   any of  and       

    D)  none of the above

    Correct Answer: A

    Solution :

                     Tertiary halide preferentially undergo \[{{\text{S}}_{\text{N}}}\text{1}\] substitution as they can give stable carbocation. \[\underset{\text{t}-\text{butyl}\,\text{chloride}}{\mathop{{{\text{H}}_{3}}C-\underset{C{{H}_{3}}}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-Cl}}\,\xrightarrow[-Cl]{slow}\underset{\text{Carbocation}}{\mathop{{{({{H}_{3}}C)}_{3}}{{C}^{+}}}}\,\xrightarrow[fast]{+O{{H}^{-}}}\]
