Electron geometry and bond angle are related as:

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˚


For O3:

  • O in the middle follows trigonal planar geometry
  • However, 1 lone pair on the top will lessen the O-O-O bond angle

Therefore, the answer is <120°


For SO3:


  • O in the middle follows trigonal planar geometry
  • No lone pairs are present in S so this will follow 120°

Therefore, the answer is 120°


For SCl2

  • This follows AX2Ewhich is tetrahedral electron geometry
  • However, 2 lone pairs are present in S

Therefore, the answer is <109.5°
