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˚
Lone pairs are treated as electron regions.
The lone pairs in the central atom will make the bond angles smaller than expected.
Arrange the following ACln species in order of decreasing Cl—A—Cl bond angles:
SCl2, OCl2, PCl3, SiCl4, SiCl62−.
