    The hybridisation found in ethylene is:

    A)  \[sp\]                  

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

    C)         \[s{{p}^{3}}\]                                   

    D)         \[s{{p}^{3}}d\]

    Correct Answer: B

    Solution :

    In ethylene \[(C{{H}_{2}}=C{{H}_{2}}),\] both carbon remains \[s{{p}^{2}}-\]hybridized. C in excited state \[=\overset{2s}{\mathop{}}\,\,\,\,\overset{2p}{\mathop{}}\,\] \[{{C}_{2}}{{H}_{4}}=\underset{{{H}_{1s}}}{\mathop{\underset{|}{\mathop{{{(s{{p}^{2}})}^{1}}}}\,}}\,\underset{{{H}_{1s}}}{\mathop{\underset{|}{\mathop{{{(s{{p}^{2}})}^{1}}}}\,}}\,\underset{{{(s{{p}^{2}})}^{1}}}{\mathop{\underset{|}{\mathop{{{(s{{p}^{2}})}^{1}}}}\,}}\,2p_{z}^{1}\]
