    In the following reaction the product will be\[C{{H}_{3}}COOH+H-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-O-H\xrightarrow[{}]{MnO}\]Product

    A)  \[HCHO\]

    B)  \[C{{H}_{3}}C{{H}_{2}}CHO\]

    C)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-H\]

    D)  \[C{{H}_{3}}OH\]

    Correct Answer: C

    Solution :

     \[C{{H}_{3}}-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-OH+H-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-OH\xrightarrow[{}]{MnO}\] \[C{{H}_{3}}-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-H+{{H}_{2}}O+C{{O}_{2}}\] This is example of decarboxylation dehydration reaction.
