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

B

Explanation

`SF_(4), H=(1)/(2)(+4-0+0)=5(sp^(3)d)`
`I_(3)^(-) , H=(1)/(2)(7+2-0+3)=6(sp^(3)d^(2))`
`(SbCl_(5))^(2-),H=(1)/(2)(5+5-0+2)=5(sp^(3)d)`
`PCl_(5) , H=(1)/(2) (5+5-0+0)=5 (sp^(3)d)`
`therefore` (b) is the correct answer.
