VSEPR Theory
  • Valence Shell Electron Pair Repulsion

7
VSEPR Theory
  • Predicts the molecular shape of a bonded molecule
  • Electrons around the central atom arrange
    themselves as far apart from each other as
    possible
  • Unshared pairs of electrons (lone pairs) on the
    central atom repel the most
  • So only look at what is connected to the central
    atom

8
These are for molecules with only paired
electrons around the central atom.
9
Linear
  • 2 atoms attached to center atom
  • 0 unshared pairs (lone pairs)
  • Bond angle 180o
  • Type AB2
  • Ex. BeF2

10
Linear
  • BeH2
  • CO2

11
Trigonal Planar
  • 3 atoms attached to center atom
  • 0 lone pairs
  • Bond angle 120o
  • Type AB3
  • Ex. AlF3

12
Trigonal Planar
  • BCl3
  • BH3

13
Tetrahedral
  • 4 atoms attached to center atom
  • 0 lone pairs
  • Bond angle 109.5o
  • Type AB4
  • Ex. CH4

14
Tetrahedral
  • PO4

15
Trigonal Bipyramidal
  • 5 atoms attached to center atom
  • 0 lone pairs
  • Bond angle
  • equatorial -gt 120o
  • axial -gt 90o
  • Type AB5
  • Ex. PF5

16
Trigonal Bipyramidal
  • PCl5

17
Octahedral
  • 6 atoms attached to center atom
  • 0 lone pairs
  • Bond angle 90o
  • Type AB6
  • Ex. SF6

18
These are for molecules with both paired and
unshared (lone) pairs of electrons around the
central atom.
19
Bent/Angular
  • 2 atoms attached to center atom
  • 1 or 2 lone pairs of electrons
  • Bond angle 104.5o
  • Type AB2E2
  • Ex. H2O

20
Bent/Angular
  • NO2

21
Trigonal Pyramidal
  • 3 atoms attached to center atom
  • 1 lone pair
  • Bond angle 107o
  • Type AB3E
  • Ex. NH3

22
Trigonal Pyramidal
  • PCl3
