Description

VSEPR Geometries All pictures in this section are from McMurry Fay, 3rd ed.

For 2 Electron Groups (density regions/charge clouds): Bond Angle: _____________ Electron Pair Geometry: _____________ Molecular Geometry _____________ For 3 Electron Groups (density regions/charge clouds): Bond Angle: _____________ Electron Pair Geometry: _____________ Molecular Geometry _____________ (3 bonds) OR _____________ (2 bonds & 1 lp)

For 4 Electron Groups (density regions/charge clouds): Bond Angle: _____________ Electron Pair Geometry: _____________ Molecular Geometry _____________ OR _____________ ( 3bonds & 1 lp) OR _____________ (2 bonds & 2 lp)

We will not be covering the geometries for 5 or 6 charge clouds Geometries for Multiple Central Atoms The geometry for more complex molecules can be predicted by combining the information from each central atom analyzed individually. Ethane

Each bond is_tetrahedral and the C-C bond can spin to provide the minimum amount of steric hindrance....
