    A) \[{{C}_{2}}{{H}_{5}}OH\]

    B) \[C{{H}_{3}}-C{{H}_{2}}-N{{H}_{2}}\]

    C) \[C{{H}_{3}}-CO-C{{H}_{3}}\]

    D) All of these

    Correct Answer: A

    Solution :

     \[C{{H}_{3}}MgI+C{{H}_{3}}-C{{H}_{2}}-N{{H}_{2}}\to \]\[C{{H}_{4}}+C{{H}_{3}}C{{H}_{2}}NHMgI\]                    \[C{{H}_{3}}MgI+{{C}_{2}}{{H}_{5}}OH\to C{{H}_{4}}+{{C}_{2}}{{H}_{5}}OMgI\] Alkyl group of Grignard?s reagent is involved in the formation of alkane.
