Element in which the 5f orbitals are only partially occupied. (Section 6.8)
atomic number (Z).
The number of protons in the nucleus of an atom. (2.3)
A cholesterol-derived detergent molecule, such as cholic acid, which is secreted by the gallbladder into the intestine to assist in the absorption of dietary lipids.
A band of molecular orbitals lying higher in energy than the occupied valence band and distinctly separated from it. (Section 12.7)
A conjugated diene or carbonyl is one in which the double bonds are separated by one single bond
coordinate covalent bond.
A bond in which the pair of electrons is supplied by one of the two bonded atoms; also called a dative bond. (9.9)
The separation on an NMR spectrum (in hertz) between adjacent peaks in a multiplet and a quantitative measure of the infl uence of the spin-spin coupling with adjacent nuclei.
A reaction involving loss of CO2, characteristic of compounds containing a carbonyl group that is beta to a COOH group.
deoxyribonucleic acids (DNA).
A type of nucleic acid. (25.4)
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 unimolecular b-elimination reaction
A compound with the structure R2CRN!NH2.
Molecular dipole moment (m)
The vector sum of individual bond dipoles.
An equation that relates the cell emf, E, to the standard emf, E°, and the reaction quotient, Q: E = E° - 1RT>nF2 ln Q. (Section 20.6)
A variety of enzymes that selectively hydrolyze specific peptide bonds.
The closeness of agreement among several measurements of the same quantity; the reproducibility of a measurement. (Section 1.5)
A voltaic cell that can be recharged. (Section 20.7)
A substitution reaction in which the solvent functions as the nucleophile.
sp3 Hybrid orbital
A hybrid atomic orbital formed by the combination of one s atomic orbital and three 2p atomic orbitals.
The conjugate base of a thiol.
