    Which of the following reaction follows\[{{S}_{N}}1\] mechanism?

    A) \[{{(C{{H}_{3}})}_{3}}C-C{{H}_{2}}Cl+C{{H}_{3}}OK\]

    B) \[{{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}Cl+KCN\]

    C)  \[{{(C{{H}_{3}})}_{3}}C-Cl+NaOH\]

    D)  \[{{(C{{H}_{3}})}_{2}}CHI+{{H}_{2}}O\]

    Correct Answer: C

    Solution :

                     \[{{(C{{H}_{3}})}_{3}}C-Cl\xrightarrow{{}}{{(C{{H}_{3}})}_{3}}C+C{{l}^{-}}\] \[{{(C{{H}_{3}})}_{3}}{{C}^{\oplus }}+NaOH\xrightarrow{{}}{{(C{{H}_{3}})}_{3}}C-OH+N{{a}^{+}}\] \[3{}^\circ \]halides undergo reaction by\[{{S}_{N}}1\]mechanism.
