    \[{{\left( {{\operatorname{CH}}_{3}} \right)}_{3}}MgCl\]on reaction with\[{{\operatorname{D}}_{2}}O\]produces:

    A) \[{{\left( {{\operatorname{CH}}_{3}} \right)}_{3}}CD\]

    B)               \[{{\left( {{\operatorname{CH}}_{3}} \right)}_{3}}OD\]

    C) \[{{\left( {{\operatorname{CD}}_{3}} \right)}_{3}}CD\]              

    D) \[{{\left( {{\operatorname{CD}}_{3}} \right)}_{3}}OD\]

    Correct Answer: A

    Solution :

    \[{{\left( C{{H}_{3}} \right)}_{3}}CD\] When it reacts with heavy water, \[{{\left( C{{H}_{3}} \right)}_{3}}MgCl+{{D}_{2}}O\to \] \[{{\left( C{{H}_{3}} \right)}_{3}}CD+Mg\left( OD \right)Cl\]
