activation energy (Ea)
The minimum energy needed for reaction; the height of the energy barrier to formation of products. (Section 14.5)
A three-dimensional plot of y2 of a wavefunction. It is a region of space that can accommodate electron density.
Avogadro’s number (NA).
6.022 3 1023; the number of particles in a mole. (3.2)
In UV-Vis spectroscopy, the region of the molecule responsible for the absorption (the conjugated p system).
Atoms or groups on an atom that are bonded to an atom that is bonded to two nonidentical groups, one of which contains a chiral center. When one of the atoms or groups is replaced by another group, a new chiral center is created and a set of diastereomers results. The hydrogens of the CH2 group of 2-butanol, for example, are diastereotopic. Diastereotopic groups have different chemical shifts under all conditions
A bimolecular b-elimination reaction.
Protons that are not interchangeable by rotational symmetry but are interchangeable by reflectional symmetry.
In Diels-Alder reactions that produce bicyclic structures, the positions that are anti to the larger bridge.
gas constant (R)
The constant of proportionality in the ideal-gas equation. (Section 10.4)
A compound in which the carbonyl group 1C “O2 occurs at the interior of a carbon chain and is therefore flanked by carbon atoms. (Section 24.4)
oxidizing agent, or oxidant
The substance that is reduced and thereby causes the oxidation of some other substance in an oxidation–reduction reaction. (Section 20.1)
An ion in which oxygen bears a positive charge.
partially condensed structures
A drawing style in which the CH bonds are not drawn explicitly, but all other bonds are drawn.
An instrument for measuring the ability of a compound to rotate the plane of plane-polarized light.
Refers to two hydrogens bonded to a carbon atom. When a different atom replaces one or the other, the carbon becomes a chiral center. The hydrogens of the CH2 group of ethanol, for example, are prochiral. Replacing one of them by deuterium gives (R)-1-deuteroethanol; replacing the other gives (S)-1-deuteroethanol
A compound that prevents a radical chain process from either getting started or continuing.
An alternative name for an imine
Atomic orbitals that are achieved by mathematically averaging one s orbital with three p orbitals to form four hybridized atomic orbitals.
The distribution among various wavelengths of the radiant energy emitted or absorbed by an object. (Section 6.3)
Compounds containing a mercapto group (SH).
