A CH3CO! group; also called an acetyl group
An OR group.
Bond dipole moment
A measure of the polarity of a covalent bond. The product of the charge on either atom of a polar bond times the distance between the atoms
A low-energy molecular orbital resulting from the constructive interference between atomic orbitals.
conjugate acid–base pair
An acid and a base, such as H2O and OH-, that differ only in the presence or absence of a proton. (Section 16.2)
The process of forming a diazonium salt by treating a primary amine with NaNO2 and HCl.
A bimolecular b-elimination reaction.
A device in which a nonspontaneous oxidation–reduction reaction is caused to occur by passage of current under a sufficient external electrical potential. (Section 20.9)
A collection of orbitals that have the same value of n. For example, the orbitals with n = 3 (the 3s, 3p, and 3d orbitals) comprise the third shell. (Section 6.5)
The point in a titration at which the added solute reacts completely with the solute present in the solution. (Section 4.6)
A reaction in which the reaction rate is proportional to the concentration of a single reactant, raised to the first power. (Section 14.4)
A process in which a carboxylic acid is converted into an ester when treated with an alcohol in the presence of an acid catalyst.
The quantity of heat required to raise the temperature of a sample of matter by 1 °C (or 1 K). (Section 5.5)
A type of isomerism involving keto (from ketone) and enol tautomers
A reaction for which the product distribution is determined by the relative rates at which the products are formed.
Triglycerides that are liquids at room temperature.
Polymers made up of repeating urethane groups, also sometimes called carbamate groups (!N!CO2!).
Hydrolysis of an ester in the presence of a base. (Section 24.4)
A polymer in which the repeating units contain chirality centers which have alternating configuration.
A geometry adopted by an atom with a steric number of 3. All three groups lie in one plane and are separated by 120°.
