    The hybridisation of carbon atoms in C?C single bond of\[HC\equiv C-CH=C{{H}_{2}}\]is

    A) \[s{{p}^{3}}-s{{p}^{3}}\]

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

    C)  \[sp-s{{p}^{2}}\]

    D)  \[s{{p}^{3}}-sp\]

    Correct Answer: C

    Solution :

     \[\underset{sp}{\mathop{HC}}\,\equiv \underset{sp}{\mathop{C}}\,-\underset{s{{p}^{2}}}{\mathop{CH}}\,=\underset{s{{p}^{2}}}{\mathop{C{{H}_{2}}}}\,\] Hence, hybridisation of carbon atoms in C?C single bond is \[sp-s{{p}^{2}}.\]
