Presentation Transcript

  1. Molecular Shape The overall shape of molecules can be predicted in most cases by the VSEPR theory V = Valence S = Shell E = Electron P= Pair R = Repulsion

  2. Molecular GeometryThe Geometry of a Molecule Reflects only the Bonded Atoms and not unbonded electrons pairs.

  3. Molecular GeometryThe Geometry of a Molecule Reflects only the Bonded Atoms and not unbonded electrons pairs.

  4. Basic angle for tetrahedral structure is 109.5 However, an unshared electron domain tends to be larger than the electron domain of shared electrons. The bond angles of the shared electrons are therefore slightly smaller, 107 

  5. Molecular Geometry of Water Geometry is “ Bent “ Bond angle in water is 104.5

  6. VSEPR Theory - Expanded OctetFive Electron Domains Trigonal Bipyramidal 90 and 120°angles

  7. VSEPR Theory - Expanded OctetSix Electron Domains Octahedral 90° angles
