    In the reaction. \[HCOOH+C{{H}_{3}}COOH\xrightarrow[\Delta ]{MnO}X;\] Product X is

    A)  \[HCHO\]

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

    C)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-O-{{C}_{2}}{{H}_{5}}\]

    D)  \[H-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-O-{{C}_{2}}{{H}_{5}}\]

    Correct Answer: B

    Solution :

     \[\underset{formic\text{ }acid}{\mathop{HCOOH}}\,+\underset{acetic\text{ }acid}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow[{}]{MnO,\Delta }\underset{acetaldehyde}{\mathop{C{{H}_{3}}CHO}}\,\] \[+{{H}_{2}}\text{O}+C{{O}_{2}}\]
