    Which of the following set of properties belong to\[PC{{l}_{5}}\]?

    A) \[s{{p}^{3}},\] tetrahedral, 4 valence shell pairs of electrons

    B)  trigonal bipyramidal, 5 valence shell pairs of electrons

    C) \[s{{p}^{3}}{{d}^{2}},\]octahedral, 6 valence shell pairs of electrons

    D) \[s{{p}^{3}}d,\]square planar, 4 valence shell pairs of electrons

    Correct Answer: B

    Solution :

     \[\text{PC}{{\text{l}}_{\text{5}}}\]molecule has \[s{{p}^{3}}d\]hybridisation. Its geometry is trigonal bipyramidal and it has 5 valence shell pairs of electrons.
