Question

Which of the following species contains exactly three $\sigma$ bond pairs and two lone pairs around the central atom, resulting in a T-shaped molecular geometry?

Prashant Kotian · Accepted Answer

Correct answer: C. In , Chlorine has 7 valence electrons. It forms 3 bonds with 3 Fluorine atoms, leaving 4 electrons (2 lone pairs). Steric number = (). Placing the 2 lone pairs in the equatorial positions minimizes repulsion, resulting in a T-shaped geometry.
