Question

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

(a) [ClO^-₃]

(b) XeF₄

(c) SF₄

(d) [I^-₃]

Answer 1

Correct option  (d) [I^-₃]

Explanation :

(a) In ClO^-₃ Cl is central atom, it is sp³-hybrid and on it one-lone pair of electrons (free pair of electrons) is present.

(b) In XeF₄, Xe is central atoms, it is sp³ d² -hybrid and on it two lone pair of electrons are present.

(c) In SF₄, S is central atom, it is sp³ d-hybrid and on it one lone pair of electrons is present.

(d) In [I₃^-], I is central atom, it is sp³ d-hybrid and on it three lone pair of electrons are present.
