Review Day - Molecular Geometry & Shapes
LEWIS DOT NOTATION
valence electrons (including ions)
kernel vs. valence electrons
octet rule
covalent molecules share electrons (use electronegativity to determine polar vs. nonpolar covalent)
molecular formula vs. structural formula
resonance
CLASSIFYING TYPES OF BONDS
properties of ionic vs covalent compounds
coordinate covalent, polar covalent, nonpolar covalent, ionic, diatomic
single, double, triple bonds (share two, four, six electrons). Triple bond is strongest and shortest.
DOMAIN GEOMETRY & MOLECULAR SHAPE
VSEPR theory
Electron Domain Geometry (EDG) linear (2), trigonal planar (3), tetrahedral (4), trigonal bipyramidal (5),
(trigonal bipyramidal (5), octahedral (6) - not on test)
Electron Domain Geometry (SHAPE) linear, trigonal planer, bent, tetrahedral, trigonal pyramidal
AB2, AB3, AB2E2, AB4, AB3E
(trigonal bipyramidal, T-shaped, see-saw, octahedral - not on test)
INTERMOLECULAR FORCES (IMF's)
dipole-dipole, hydrogen bonding (between H...N, O, F), London Dispersion Forces
POLARITY & SOLUBILITY
"like dissolves like"
+--> more negative end
