Question

what is the molecular geometry for the pbr3 molecule?
bent
tetrahedral
trigonal planar
trigonal pyramidal
linear

Explanation:

In $PBr_3$, the phosphorus atom has 5 valence electrons. It forms 3 bonds with bromine atoms and has 1 lone - pair. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, the presence of 3 bonding pairs and 1 lone - pair around the central atom results in a trigonal pyramidal molecular geometry.

Answer:

trigonal pyramidal
