Question

Quizplus · Accepted Answer

The central atom of PF₅ is P, which has five electron groups: one lone pair and four bonding pairs. This gives it a trigonal bipyramidal electron geometry. The molecular geometry is also trigonal bipyramidal because all five electron groups are bonding pairs (there are no lone pair repulsions to distort the shape). Choice A is the only option that matches both the electron and molecular geometries.
