    \[{{(C{{H}_{3}})}_{3}}CMgCl\]on reaction with \[{{D}_{2}}O\] produces

    A) \[{{(C{{H}_{3}})}_{3}}COD\]

    B)        \[{{(C{{D}_{3}})}_{3}}CH\]

    C) \[{{(C{{H}_{3}})}_{3}}CD\]           

    D)        \[{{(C{{D}_{3}})}_{3}}CD\]

    E) \[{{(C{{D}_{3}})}_{3}}COD\]

    Correct Answer: C

    Solution :

    \[\underset{Grignard\text{ }reagent}{\mathop{{{(C{{H}_{3}})}_{3}}C-MgCl}}\,+D.OD\xrightarrow{{}}{{(C{{H}_{3}})}_{3}}C.D\] \[+MgCl(OD)\] [Grignard reagent when reacts with a protic solvent, gives alkane.]
