activity
The decay rate of a radioactive material, generally expressed as the number of disintegrations per unit time. (Section 21.4)

alkaline earth metals
Members of group 2A in the periodic table. (Section 7.7)

Alkylation reaction
Any reaction in which a new carboncarbon bond to an alkyl group is formed.

annulenes
Compounds consisting of a single ring containing a fully conjugated p system. Benzene is [6]annulene.

benzylic position
A carbon atom that is immediately adjacent to a benzene ring.

bonding pair
In a Lewis structure a pair of electrons that is shared by two atoms. (Section 9.2)

carbonyl group
A CRO bond. carboxylic acid derivative (Sect. 21.6): A compound that is similar in structure to a carboxylic acid (RCOOH) but the OH group of the carboxylic acid has been replaced with a different group, Z, where Z is a heteroatom such as Cl, O, N, etc. Nitriles (R!C#N) are also considered to be carboxylic acid derivatives because they have the same oxidation state as carboxylic acids.

catenation.
The ability of the atoms of an element to form bonds with one another. (22.3)

Constitutional isomers
Compounds with the same molecular formula but a different connectivity of their atoms

electrophile
A compound containing an electrondeficient atom that is capable of accepting a pair of electrons.

frontier orbitals
The highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) that participate in a reaction.

functional group
An atom or group of atoms that imparts characteristic chemical properties to an organic compound. (Section 24.1)

Meisenheimer complex
Theresonancestabilized intermediate of a nucleophilicaromatic substitution reaction.

noble gases
Members of group 8A in the periodic table. (Section 7.8)

progestins
Female sex hormones.

rare earth element
See lanthanide element. (Sections 6.8 and 6.9)

reaction mechanism
A series of intermediates and curved arrows that show howthe reaction occurs in terms of the motion of electrons.

S
A term used to designate the configuration of a chirality center, determined in the following way: Each of the four groups is assigned a priority, and the molecule is then rotated (if necessary) so that the #4 group is directed behind the page (on a dash). A counterclockwise sequence for 123 is designated as S.

scis
A conformation of a conjugated diene in which the disposition of the two p bonds with regard to the connecting single bond is cislike (a dihedral angle of 0°).

Z
For alkenes, a stereodescriptor that indicates that the two priority groups are on the same side of the p bond.
