  • question_answer
    Which of the following compounds will form a hydrocarbon on reaction with Grignard reagent [CPMT 1988, 93]

    A) \[C{{H}_{3}}C{{H}_{2}}OH\]

    B) \[C{{H}_{3}}CHO\]

    C) \[C{{H}_{3}}COC{{H}_{3}}\]

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

    Correct Answer: A

    Solution :

               Compounds having active hydrogen \[\left( ROH,{{H}_{2}}O,R-N{{H}_{2}} \right)\] can form alkane when treated with Grignard?s reagent \[C{{H}_{3}}C{{H}_{2}}OH+C{{H}_{3}}MgBr\to C{{H}_{4}}\]\[+Mg<\begin{matrix}    Br\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,  \\    OC{{H}_{2}}C{{H}_{3}}  \\ \end{matrix}\]
