In which one of the following species , the central atom has the tuype of hybdridiztion which is not the same as that present in other three?

Options

A. `SF_4`
B. `I_3^-`
C. `SbCl_5^(2-)`
D. `PCl_5`

Answer

C

Explanation

Key Idea Molecules having same hybridisation have same number of hybrid orbitals.
`H=1/2[V+X-C+A]`
where, V=number of valence electrons of central atom
X=number of monovalent atoms
C=charge on cation
A=charge on anion
`SbCl_5^(2-)=sp^3d^2, PCl_5=sp^3d`
`SF_4=sp^3d, I_3^(-)=sp^3d`
