The electron-pair geometry and molecular geometry of XeF₄ are ________ and ________,respectively.

Question

Quizplus · Accepted Answer

The central atom Xe has 6 electron pairs; 4 from F and 2 from S. Therefore, the electron-pair geometry is octahedral (6 regions of electron density). 
The molecular geometry depends on the number of lone pairs on the central atom. In this case, there is one lone pair on Xe, which will occupy one of the equatorial positions. This arrangement gives a square planar molecular geometry.
