Absolute confi guration
Which of the two possible isomers an enantiomer is (i.e., whether it is the right- or left-handed isomer).
A list of metals in order of decreasing ease of oxidation. (Section 4.4)
The amount of product actually obtained in a reaction. (3.10)
An unsaturated hydrocarbon that contains one or more carbon-carbon triple bonds.
A conformation about a single bond in which two groups on adjacent carbons lie at a dihedral angle of 180°.
The basic unit of an element that can enter into chemical combination. (2.2)
base-dissociation constant (Kb)
An equilibrium constant that expresses the extent to which a base reacts with solvent water, accepting a proton and forming OH-1aq2. (Section 16.7)
The most common drawing style employed by organic chemists. All carbon atoms and most hydrogen atoms are implied but not explicitly drawn in a bond-line structure.
A polymerization that involves sequential addition reactions, either to unsaturated monomers or to monomers possessing other reactive functional groups.
A bond in which two electrons are shared by two atoms. (9.4)
A cyclic ether in which oxygen is one atom of a three-membered ring
law of definite proportions
A law that states that the elemental composition of a pure substance is always the same, regardless of its source; also called the law of constant composition. (Section 1.2)
Finely powdered palladium metal deposited on solid calcium carbonate that has been specially modifi ed with lead salts. Its particular use is as a catalyst for the reduction of an alkyne to a cis alkene
London dispersion forces
Attractive forces between transient dipole moments, observed in alkanes.
Addition of a reagent to a metal center causing it to add two substituents and to increase its oxidation state by two
The SI unit of pressure: 1 Pa = 1 N >m2 . (Section 10.2)
A polymer of amino acids that has a molecular weight of less than 10,000. (Section 24.7)
A term used to indicate that exactly two alkyl groups are attached directly to a particular position. For example, a secondary carbocation has two alkyl groups attached directly to the electrophilic carbon atom (C+).
An atom, most commonly carbon, about which exchange of two groups produces a stereoisomer. Chiral centers are one type of stereocenter
An ester of glycerol with three fatty acids
