A class of colored compounds that are formed via azo coupling.
A separation method involving passing a vapor or solution mixture through a column packed with a material with different affi nities for different components of the mixture.
A dispersion of particles of one substance (the dispersed phase) throughout a dispersing medium made of another substance. (12.8)
The mass of a substance divided by its volume. (1.6)
An effect that causes different regions of space to be characterized by different magnetic field strengths.
Incorporation of a hetero atom into a solid to change its electrical properties. For example, incorporation of P into Si. (Section 12.7)
A symbol used to show that structures on either side of it are resonance-contributing structures
electrophilic aromatic substitution
A substitution reaction in which an aromatic proton is replaced by an electrophile and the aromatic moiety is preserved.
enthalpy of formation
The enthalpy change that accompanies the formation of a substance from the most stable forms of its component elements. (Section 5.7)
The joining of two light nuclei to form a more massive one. (Section 21.6)
A property that is independent of the amount of material considered, for example, density. (Section 1.3)
A cyclic amide.
localized lone pair
A lone pair thatis not participating in resonance.
A pair of unshared, or nonbonding, electrons.
Refers to groups occupying l,2-positions on a benzene ring.
A group that directs the regiochemistry of an electrophilic aromatic substitution reaction such that the incoming electrophile is installed at the ortho or para positions.
Primary structure of proteins
The sequence of amino acids in the polypeptide chain, read from the N-terminal amino acid to the C-terminal amino acid.
ribonucleic acid (RNA)
A polynucleotide in which ribose is the sugar component. (Section 24.10)
A conformation of a conjugateddiene in which the disposition of the two p bonds with regard to the connecting single bond is translike (a dihedral angle of 180°).
A polymer in which its growing chains are terminated by formation of new functional groups at both ends of its chains. These new functional groups are introduced by adding reagents, such as CO2 or ethylene oxide, to the growing chains.
