Review Sheet Structural Formulas (Lewis Structures: structural formula that used dots and lines to describe bonding. Molecular Geometry: Shape of a molecule based on number of bonded atoms and lone pairs on an atom Ball and Stick Model: three dimensional physical model of molecular shape. VSEPR Theory: In a small molecule, the pairs of valence electrons are arranged as far apart from each other as possible. Bonded Pair: electrons in a bond between two atoms Unbonded Pair: electrons not involved in a bond (lone pair) Substituent: a bonded or unbonded pair on an atom Bond Angle: Angle formed by neighboring atoms

Review Sheet Hybrid Orbital: a mixture (or blended) orbital Polarity: unequal sharing of electrons in a bond Bond Polarity: direction of the unequal sharing of electrons in a bond Molecule Polarity: overall direction of polarity in a molecule Dipole: a polar molecule (one that has a positive end and a negative end) Intermolecular Force: a force of attraction that exists between neighboring molecules because of their polarity Dipole-Dipole Attraction: Attraction between neighboring dipoles Hydrogen Bond: strong dipole bond between the hydrogen atom of a molecule and a highly electronegative atom of another molecule such as F, O or N.
