    \[C{{H}_{3}}CHO+G.R.\xrightarrow{{}}X\]product is:

    A)  \[{{(C{{H}_{3}})}_{2}}CHOH\]

    B)  \[C{{H}_{3}}-O-C{{H}_{2}}\]

    C)  \[C{{H}_{3}}OH\]      

    D)  \[C{{H}_{3}}COOH\]

    Correct Answer: A

    Solution :

    \[\underset{Acetaldehyde}{\mathop{C{{H}_{3}}CHO}}\,+\underset{G.R}{\mathop{C{{H}_{3}}MgBr}}\,\xrightarrow{{}}\] \[C{{H}_{3}}-\underset{H}{\mathop{\underset{|}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OMgBr\xrightarrow{H.\,OH/{{H}^{+}}}\]                 \[{{(C{{H}_{3}})}_{2}}CHOH+Mg(OH)Br\]
