    The geometry of the hybrid orbital, which contains \[20%\] \[s-\]character is:

    A)  octahedral

    B)  tetrahedral

    C)  trigonal bipyramidal

    D)   square planar

    Correct Answer: C

    Solution :

    Key Idea: Write the name of orbitals which are participating in bond formation and then calculate percentage.
    Hybridisation Orbitals % of\[\mathbf{s}\]character
    [a] Octahedral \[s{{p}^{3}}{{d}^{2}}\] \[16.7%\]
    [b] Tetrahedral \[s{{p}^{3}}\] \[25%\]
    [c] Trigonal bipyramidal \[s{{p}^{3}}d\] \[20%\]
    [d] Square planar \[s{{p}^{3}}{{d}^{2}}\] \[16.7%\]
