    \[CH\equiv CH+HgS{{O}_{4}}\xrightarrow{{{H}_{2}}O}A,\] A is:

    A)  \[C{{H}_{2}}=C{{H}_{2}}~\]

    B)  \[{{C}_{2}}{{H}_{5}}OH\]

    C)  \[HCHO\]     

    D)  acetaldehyde

    Correct Answer: D

    Solution :

    \[CH\equiv CH+{{H}_{2}}O\xrightarrow[HgS{{O}_{4}}]{{{H}_{2}}S{{O}_{4}}}C{{H}_{2}}=\underset{OH}{\mathop{\underset{|}{\mathop{C}}\,}}\,H\] \[\xrightarrow{ketonization}\underset{\text{Acetaldehyde}}{\mathop{C{{H}_{3}}.CHO}}\,\]
