    Et. \[MgBr+C{{O}_{2}}\to \]Product is:

    A)  \[{{C}_{3}}{{H}_{7}}COOH\]

    B)  \[{{C}_{2}}{{H}_{5}}COOH\]

    C)  \[{{C}_{4}}{{H}_{9}}COOH\]

    D)  \[HCOOH\]

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}MgBr+O=C=O\xrightarrow{{}}\] \[C{{H}_{3}}-C{{H}_{2}}\underset{{{H}^{+}}\downarrow {{H}_{2}}O}{\mathop{-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-}}\,OMgBr\]
