5 Electron Geometry vs Molecular Geometry
4 pairs of electrons require 4 electron orbitals shape of molecule depends on nuclei only shape for molecule is TRIGONAL PYRAMIDAL tetrahedral arrangement of electrons

6 Electron Geometry vs Molecular Geometry
4 pairs of electrons require 4 electron orbitals shape of molecule depends on nuclei only tetrahedral arrangement of electrons shape for molecule is BENT

7 Electron Geometry vs Molecular Geometry
3 pairs of electrons require 3 electron orbitals shape of molecule depends on nuclei only shape for molecule is BENT trigonal planar arrangement of electrons

8 4 electron pairs, 1 lone pair

9 4 electron pairs, 2 lone pairs
