Question

using the vsepr model, predict the molecular geometry of xef4. select the single best answer. trigonal planar tetrahedral linear t - shaped seesaw square planar trigonal pyramidal octahedral square pyramidal bent

Explanation:

First, find the central atom (Xe) valence - electron number (8). Then, consider the number of bonding pairs (4, from 4 F atoms) and lone pairs (2). According to VSEPR, with 6 electron - pair groups (4 bonding + 2 lone) around the central atom, the electron - pair geometry is octahedral. But the molecular geometry, ignoring the lone pairs, is square planar.

Answer:

square planar
