Use VSEPR rules to predict the shapes and geometries of the central atoms of the following:

  • BeH2
  • [BeF4]2-
  • SF6
  • [IO3]-
  • [IO4]-
  • [IO6]5-
  • [GaBr4]-
  • [NCS]-
  • [SnPh3]-
  • SO2
  • SO3
  • SOCl2
  • SO2Cl2
  • MeC≡N
  • HC≡CH
  • H2CCH2
  • CO2
  • [CO3]2-
  • [NO3]-
  • NH2-
  • XeOF4
  • [SbCl6]-
  • [H3O]+
  • [NH4]+
  • IF5
  • [AlCl6]3-
  • Me-
  • SbPh5
  • [SO4]2-
  • O3
  • Me2SO
  • PCl3
  • [SbO4]3-

Confirm for which compounds your predicted geometries are correct by referring to appropriate textbooks.

Use the VSEPR rules to predict the coordination geometries of:

  • XeF2
  • [IF4]-
  • SF4

Write down reasonable isomers for your predicted geometries and determine in each case which isomer is the most likely.
