Question

Quizplus · Accepted Answer

The electron geometry of XeF₂ is trigonal bipyramidal because Xe has six electron domains around it (one lone pair, two axial F atoms, and three equatorial B12S1U1 atoms). However, the molecular geometry is linear because the lone pair on Xe occupies one of the equatorial positions, causing the two axial F atoms to move closer together and giving a linear shape. Choice D is the only option that correctly matches the electron and molecular geometries.
