We can determine the electron geometry and bond angle using this:
Electron Regions Electronic Geometry Bond Angles
2 linear 180˚
3 trigonal planar 120˚
4 tetrahedral 109.5˚
5 trigonal bipyramidal 90˚, 120˚, and 180˚
6 octahedral 90˚ and 180˚
Step 1: Xe (less electronegative than chlorine) so Xe is the central atom.
Step 2: The total number of valence electrons present in XeCl2 is:
Group Valence Electrons
Xe 8A 1 × 8 e– = 8 e–
Cl 7A 2 × 7 e– = 14 e–
Total: 22 valence e–
Step 3: Halogens, when not the central atom, form only 1 bond.
Predict the molecular structure (including bond angle) of the following.
