    \[C{{H}_{3}}CHO+Se{{O}_{2}}\xrightarrow{\text{Acetic}\,\text{acid}}\,A,\] A will be

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

    B)  \[\underset{CHO}{\overset{CHO}{\mathop{|}}}\,\]

    C)  \[\begin{align}   & COOH \\  & | \\  & COOH \\ \end{align}\]                     

    D)  \[\begin{align}   & CHO \\  & | \\  & COOH \\ \end{align}\]

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}CHO\xrightarrow[C{{H}_{3}}COOH]{Se{{O}_{2}}}\,\underset{CHO}{\overset{CHO}{\mathop{|}}}\,\]
