    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 s character
    Octahedral \[s{{p}^{3}}{{d}^{2}}\] 16.7%
    Tetrahedral \[s{{p}^{3}}\] 25%
    Trigonal bipyramidal \[s{{p}^{3}}d\] 20%
    Square planar \[s{{p}^{3}}{{d}^{2}}\] 16.7%
