Which is the most reasonable prediction for the three F-Br-F bond angles in BrF₃?

Question

Quizplus · Accepted Answer

According to the VSEPR theory, the central atom (S) in BrF₃ has five electron pairs around it (one from each surrounding atom and three lone pairs). The lone pairs will repel each other more than the bonded pairs, resulting in a distortion of the molecule from the ideal tetrahedral shape. This distortion corresponds to a smaller bond angle between the F-S-F bonds (86°) and a larger angle between the lone pairs and the surrounding atoms (172°). The F-Br-F angle should also be 86°, as it is determined by the lone pairs' repulsion rather than the bonded pairs.
