    In the hydrogenation reaction given below, the hybrid state of the carbon atom changes from: \[{{C}_{2}}{{H}_{2}}\xrightarrow{{{H}_{2}}/Ni}{{C}_{2}}{{H}_{4}}\xrightarrow{{{H}_{2}}/Ni}{{C}_{2}}{{H}_{6}}\]

    A)  \[sp-s{{p}^{2}}-s{{p}^{3}}\]

    B)         \[s{{p}^{3}}-s{{p}^{2}}-sp\]

    C)         \[s{{p}^{2}}-sp-s{{p}^{3}}\]

    D)         \[s{{p}^{3}}-sp-s{{p}^{2}}\]

    Correct Answer: A

    Solution :

    Carbon atom undergoes \[sp,\,s{{p}^{2}}\] and \[s{{p}^{3}}\text{-}\]hybridisation in \[{{C}_{2}}{{H}_{2}},\]\[{{C}_{2}}{{H}_{4}}\]and \[{{C}_{2}}{{H}_{6}}\] respectively.
