The most stable form of BrF₃ has both lone pair of electrons in the equatorial plane. In this orientation, what is the number of lone pair - base pair repulsions at 90˚? A) 0 B) 1 C) 2 D) 3 E) 4

Question

Quizplus · Accepted Answer

Lone pair-base pair repulsions occur when a lone pair of electrons on one atom is close to a lone pair of electrons on another atom. In the most stable form of BrF3, both lone pairs of electrons are in the equatorial plane, which means they are as far away from the three fluorine atoms as possible. This orientation minimizes lone pair-base pair repulsions.
