absolute temperature scale.
A temperature scale that uses the absolute zero of temperature as the lowest temperature. (5.3)
Reactions that are characterized by the addition of two groups across a double bond. In the process, the pi (p) bond is broken.
An organic compound containing at least one halogen.
A solid whose molecular arrangement lacks the regularly repeating long- range pattern of a crystal. (Section 12.2)
Compounds that will react with either acids or bases. Amino acids are amphoteric.
Orbitals fi ll in order of increasing energy, from lowest to highest.
The peak caused by the most abundant ion in a mass spectrum; the most intense peak. It is assigned an arbitrary intensity of 100
The enthalpy change, ?H, required to break a particular bond when the substance is in the gas phase. (Section 8.8)
dipole moment (m)
The amount of partial charge (d ) on either end of a dipole multiplied by the distance of separation (d): m=d × d
A property that depends on the amount of material considered; for example, mass or volume. (Section 1.3)
A simple method for drawing the relative energy levels of the MOs for a ring assembled from continuously overlapping p orbitals.
A cyclic compound containing at least one heteroatom (such as S, N, or O) in the ring.
Homolytic bond cleavage
Cleavage of a bond so that each fragment retains one electron; formation of radicals.
law of constant composition
A law that states that the elemental composition of a pure compound is always the same, regardless of its source; also called the law of definite proportions. (Section 1.2)
nucleophilic aromatic substitution
A substitution reaction in which an aromatic ring is attacked by a nucleophile, which replaces a leaving group.
pi 1P2 molecular orbital
A molecular orbital that concentrates the electron density on opposite sides of an imaginary line that passes through the nuclei. (Section 9.8)
A macromolecule containing many amino acid units, each joined to the next by a peptide bond
Shielding in NMR
Also called diamagnetic shielding; the term refers to the reduction in magnetic fi eld strength experienced by a nucleus underneath electron density induced to circulate when the molecule is placed in a strong magnetic fi eld.
Common name for silicon dioxide. (Section 22.4)
A compound containing an !SH (sulfhydryl) group bonded to an sp3 -hybridized carbon.
