In which of the following, `d_(x^(2) - y^(2))` orbital is not participate in its hybridisation ?

Options

A. `PCl_(5)`
B. `SF_(6)`
C. `XeF_(4)`
D. `IF_(7)`

Answer

A

Explanation

Orbitals used in a hybridisation
(A) `PCl_(5) " " S + P_(x) + P_(y) + P_(z) + d_(z^(2))`
(B) `SF_(6) " " S + P_(x) + P_(y) + P_(z) + d_(z^(2)) + d_(x^(2) - y^(2))`
(C ) `XeF_(4) " " S + P_(x) + P_(y) + P_(z) + d_(z^(2)) + d_(x^(2) - y^(2))`
(D) `IF_(7) " " S + P_(x) + P_(y) + P_(z) + d_(z^(2)) + d_(x^(2) - y^(2)) + d_(xy)`
