Which species has the maximum number of lone pair of electrons on the central atom ?

Options

A. `[CIO_(3)]^(-)`
B. `XeF_(4)`
C. `SF_(4)`
D. `[I_(3)]^(-)`

Answer

D

Explanation

(a) In `CIO_(3)^(-)`, CI is central atom, it is `sp^(3)` hybride and on it one lone pair of electrons (free pair of electron) is presents

(b) In `XeF_(3), Xe` is central atom, it is `sp^(2)d^(2)` hybride and on it two lone pair of electrons are presents

(c) In `SF_(4) S`, is central atom, it is `sp^(3)d` hybride and on it one lone pair of electrons is presents

(d) In `[I_(3)^(-)], I`, CI is central atom, it is `sp^(3)d` hybride and on it one lone pair of electrons are presents
