(a) bonding between cations and anions resulting from electrostatic attractions of opposite charges
(b) a covalent bond that involves the sharing of two pairs of electrons
(c) a group of atoms substituted for hydrogen in the formula of a hydrocarbon that gives the compound its characteristic properties
(d) representation of an atom consisting of the symbol for the element surrounded by a number of dots equal to the number of valence electrons
(e) the angle between the two lines defined by a central atom attached to two surrounding atoms
(f) a bond resulting from the equal sharing of electron pairs
(g) a hydrocarbon containing carbon-carbon double bonds
(h) the separation of electronic charge within a bond (or molecule)
(i) a class of chemical compounds containing only carbon and hydrogen
(j) an average or composite Lewis formula derived from two or more valid Lewis formulas that closely represents the bonding in a molecule
(k) a hydrocarbon derivative containing the –OH group
(l) the shapes of molecules result from the tendency for electron pairs to maximize the distance between them to minimize repulsions
