In which of the following species, d-obitals having xz an yz two nodal planes involved in hybridization of central atoms?

Options

A. `IO_(2)F_(2)^(-)`
B. `ClF_(4)^(-)`
C. `IF_(7)`
D. None of these

Answer

C

Explanation

`IO_(2)F_(2)^(-): Hyb. sp^(3)d[equivsp_(x)d_(y)d_(z)d_(x^(2)]`
`ClF_(4)^(-): Hyb. sp^(3)d^(2)[equivsp_(x)d_(y)d_(z)d_(x^(2)-y^(2))d_(x^(2)]`
`IF_(7): Hyb. sp^(3)d^(3))[equivsp_(x)d_(y)d_(z)d_(x^(2)-y^(2))d_(xy)d_(x^(2)]`
`d_(xy)` : orbitals has two nodal planes xz and zy
