Question

In which one of the following species the central atom has the type of hybridization which is not the same as that present in the other three:

(A) PCl5 

(B) SF4 

(C) I3− 

(D) SbCl52− 

Answer 1

To predict the hybridization of the molecule by using the below formula,

H=1/2[V+M−C+A]

Where H = number of orbitals in hybridization

V = valence electrons in central atom

C = charge on cation

A = charge on the anion

M = number of monovalent atom

ForSbCl52−, V = 5, A = 2, and M =5

-The number of orbitals in hybridization, H = 1/2[5+5+2] = 6

-Hence, H =6, then SbCl−25 undergoes sp3d2 hybridization.

-Among all given species, SbCl5−2 differs in hybridization

 

 

SbCl5²- hybridization is different from others.
