    \[C{{H}_{3}}C{{H}_{2}}C\equiv CH\xrightarrow[{}]{R}bu\tan one-2.\text{ }R\]is:

    A)  \[H{{g}^{2+}}/dil.\,{{H}_{2}}S{{O}_{4}}\]

    B)  \[KMn{{O}_{4}}\]

    C)  \[KCl{{O}_{3}}\]

    D)  \[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\]

    Correct Answer: A

    Solution :

                     Alkyne forms carbonyl compounds on hydrolysis in presence of mercury salt. \[C{{H}_{3}}C{{H}_{2}}C\equiv CH\xrightarrow[H{{g}^{2+}}/{{H}_{2}}S{{O}_{4}}]{HOH}\underset{bu\tan one-2}{\mathop{C{{H}_{3}}C{{h}_{2}}COC{{H}_{3}}}}\,\]
