Question Analysis
This question tests the student's understanding of the relationship between the number of bonding pairs and lone pairs in determining the molecular geometry.

Key Concept Explanation
In VSEPR theory:
Trigonal bipyramidal geometry corresponds to 5 total electron domains around the central atom.
Bonding pairs are electron domains involved in bonds.
Lone pairs are electron domains not shared with another atom.
The relationship is: Total electron domains = bonding pairs + lone pairs
