Question

Among \(XeO_3F_2\), \(ICl_2^-\), \(ClO^-\) and \(SO_3^{2-}\), the number of species having three lone pairs of electrons on the central atom according to VSEPR theory is:

• A. 3
• B. 0
• C. 4
• D. 2

Hint:

Find the steric number and lone pair count on the central atom of each species using VSEPR/AXE notation.

Answer 1

The Correct Option is D

AXnEm notation: XeO3F2 AX5E0; ICl2- AX2E3; ClO- AX1E3; SO3(2-) AX3E1. Species with E=3: ICl2- and ClO-, total 2.

\[\boxed{(D)\ 2}\]
