Final answer:
The electronic geometry of KrF₂ is trigonal bipyramidal with a linear molecular structure due to the arrangement of five electron pairs around the central xenon atom, leading to a 180° bond angle.
Step-by-step explanation:
The electronic geometry of KrF₂ can be predicted using VSEPR (Valence Shell Electron Pair Repulsion) theory. Xenon (Xe) in XeF₂ has three lone pairs and two bonding pairs of electrons. This leads to a total of five electron pairs, which arrange themselves in a trigonal bipyramidal geometry with the lone pairs occupying the equatorial positions. This results in the two fluoride atoms to be positioned at the axial points, giving XeF₂ a linear molecular structure and a 180° bond angle.
