    Identify the product \[Y\] in the sequence \[C{{H}_{3}}CHO+C{{H}_{3}}Mgl\xrightarrow{\text{Ether}}X\xrightarrow{{{H}_{2}}O/{{H}^{+}}}Y\] [Kerala (Med.) 2001]

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

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

    C)                 \[{{(C{{H}_{3}})}_{2}}CHOH\]     

    D)                 \[{{(C{{H}_{3}})}_{3}}COH\]

    Correct Answer: C

    Solution :

               \[C{{H}_{3}}MgI+C{{H}_{3}}CHO\to \left[ C{{H}_{3}}-\underset{C{{H}_{3}}\,\,}{\overset{OMgI}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,\,\,\,}{\overset{|\,\,\,\,\,\,\,\,\,\,\,\,\,}{\mathop{C-H}}}\,}}}\, \right]\]\[\xrightarrow{{{H}_{3}}{{O}^{+}}}\underset{2-\text{Propanol}}{\mathop{{{(C{{H}_{3}})}_{2}}CHOH}}\,\]
