    The d orbital involved in the hybridisation in the\[PC{{l}_{5}}\]molecule is

    A)  \[3{{d}_{{{x}^{2}}-{{y}^{2}}}}\]                                 

    B)  \[3{{d}_{{{z}^{2}}}}\]

    C)  \[3{{d}_{xy}}\]                                

    D)  \[4{{d}_{{{x}^{2}}-{{y}^{2}}}}\]

    Correct Answer: B

    Solution :

                    In \[PC{{l}_{5}},\] No. of hybrid orbitals = no. of o bonds + lone pair \[=5+0=5\] Thus, hybridisation is\[s{{p}^{3}}d.\]. The d-orbital involved in the sp3d hybridisation i\[3{{d}_{{{z}^{2}}}}\].
