Answer» Correct Answer - D Hybridisation is calculated by steric number rule. Steric no =no of atoms attached to central atom + no of lone pairs present on central atom. Steric no for `IO_4^(-)=4+0=4 " " sp^3` , Steric no for `IC l_4^(-)`=4+2=6 `" "sp^3d^2` Steric no for `IF_4^(+)`=4+1=5 `sp^3d`, Steric no for `SO_3`3+0=3 `" "sp^2` Steric no for `PCl_4^(+)`=4+0=4 `sp^3` , Steric no for `BF_4^-` =4+0=4 `sp^3` Steric no for `XeO_3`=3+1=4 `sp^3` , Steric no for `XeO_4`=4+0=4 `sp^3`Steric no for `XeF_4`=4+2=6 `sp^3d^2`, Steric no for `CIO_4^-` =4+0=4 `sp^3` |
