Molecular Geometry and VESPR Theory (3.5)
Structure = Function Molecule Polarity
Structure = Function Attraction between molecules
Structure = Function Reactivity
VESPR Lone Pair electrons vs VESPR Lone Pair electrons vs. Shared electrons (bonds) Sulfur is the central atom
Sigma (σ) and Pi (π) Bonds
Sigma Bond orientation Head to head orientation
Pi Bond orientation Side by side
Planar Molecules These atoms are arranged in one plane of view.Imagine them being drawn on a piece of paper.
Linear molecules
Trigonal Planear
Bent or Angular Planar 1 Lone Pair
3 – dimensional These shapes occur in 3 dimensions 1) Up/down 2) left/right 3) forward/backward
Bent or Angular Pyramidal 2 lone pairs
Tetrahedral
Trigonal-Pyramidal 1 lone pair
Trigonal Bi-pyramidal
Octahedral Four sides per pyramid
Hybridization All 2sp orbitals have the same amount of energy
Hybridized compound
