Title: Review Day
Description: Honors Chemistry
January 12, 2021

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
