instantaneous dipole - anSWER-a temporary change in charge distribution
volatility - anSWER-substance's tendency to vaporize
frequency factor (in the Arrhenius Equation) - anSWER-Number of times the
reactants approach the activation barrier per unit time
elementary step - anSWER-A step within the reaction mechanism, which cannot
be broken down into smaller steps. The molecularity of the step can be linked to
a rate law (i.e. first order, second order, zero order)
catalyst - anSWER-substance that increases the rate of reaction without being
consumed
what does the equilibrium constant represent - anSWER-the relationship between
products and reactants of a reaction at equilibrium
amphoteric substances - anSWER-Substances that can react as both acids and
bases, such as H20 and NH3
strong acids - anSWER-HCl, HBr, HNO3, H2SO4, HClO4
weak acids - anSWER-carboxylic acids, acetic acid, hydrofluoric acid
strong bases - anSWER-NaOH, KOH
, weak bases - anSWER-NH3, amines (anything with NH2)
functional group - anSWER-group of atoms within a molecule having
characteristic chemical behavior
alkanes - anSWER-saturated, single bonds
alkenes - anSWER-have unsaturated, double bonds
alkynes - anSWER-have unsaturated, triple bonds
arenes - anSWER-have alternating double/single bonds, often in an "aromatic
ring"
benzene is an example
alcohol - anSWER-carbon atom bonded to oxygen of hydroxyl group (-OH)
polar, water soluble
increasing hydrocarbon size decreases solubility
carboxylic acid - anSWER--OH group bonded to C and O double bond
gives up a proton-deprotonated group called carboxylate
amines - anSWER-carbons bonded to nitrogen
