  • question_answer Which type of hybridisation occurs in ethylene [CBSE PMT 1991; Bihar MEE 1996; JIPMER 1997]

    A) sp

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

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

    D) \[s{{p}^{3}}d\]

    Correct Answer: B

    Solution :

    \[H-\underset{H\,}{\mathop{\underset{|\,\,\,\,}{\mathop{\overset{s{{p}^{2}}}{\mathop{C\,\,}}\,}}\,}}\,=\,\underset{H\,\,}{\mathop{\underset{|\,\,\,\,}{\mathop{\overset{s{{p}^{2}}}{\mathop{C\,-}}\,}}\,}}\,H\]  \[s{{p}^{2}}\]-hybridisation (trigonal planar).
