Any reaction in which an atom or group of atoms is substituted for another atom or group of atoms at an allylic carbon.
A reaction for which the reagent necessary to catalyze the reaction is produced by the reaction itself.
The C “O double bond, a characteristic feature of several organic functional groups, such as ketones and aldehydes. (Section 24.4)
A step in a chain reaction characterized by the formation of reactive intermediates (radicals, anions, or cations) from nonradical or noncharged molecules
The 3D spatial orientation of the groups connected to a chirality center (R or S ) or of the groups in a stereoisiomeric alkene (E or Z).
A substance formed by addition of a proton to a Brønsted–Lowry base. (Section 16.2)
A bond formed between two or more atoms by a sharing of electrons. (Section 8.1)
deoxyribonucleic acids (DNA).
A type of nucleic acid. (25.4)
Refers to a substance that rotates the plane of polarized light to the right

Therange of all frequencies of electromagnetic radiation,which is arbitrarily divided into severalregions, most commonly by wavelength.
See voltaic cell. (Section 20.3)
Heat of combustion (DH0 )
Standard heat of combustion is the heat released when one mole of a substance in its standard state (gas, liquid, solid) is oxidized completely to carbon dioxide and water.
A drawing style that is designed to show the conformation of a molecule.
An industrial process used to make nitric acid from ammonia. The NH3 is catalytically oxidized by O2 to form NO; NO in air is oxidized to NO2; HNO3 is formed in a disproportionation reaction when NO2 dissolves in water. (Section 22.7)

Quaternary (4°) ammonium ion
An ion in which nitrogen is bonded to four carbons and bears a positive charge
radioactive decay chain
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one. Also called nuclear disintegration series. (Section 21.2)
The starting alkyl halide in a substitution or elimination reaction.
A reaction for which the ratio of products is determined solely by the distribution of energy among the products.
