Select number of molecules/ions in which central atom uses its `d_(z^(2))` orbital in hybridisation.
`XeF_(6),SOF_(4),NO_(3)^(-),ClO_(3)^(-),BrF_(3),IF_(4)^(-),COCl_(2),PCl_(6)^(-)`

Answer

5

Explanation

`XeF_(6)rarrsp^(3)d^(2),SOF_(4)rarrsp^(3)d,NO_(3)^(-)rarrsp^(2),`
`ClO_(3)^(-)rarrsp^(3),BrF_(3)rarrsp^(3)d,IF_(4)^(Theta)rarrsp^(3)d^(2),`
`COCl_(2)rarrsp^(2),PCl_(6)^(-)rarrsp^(3)d^(2)`
