An amino acid in which the amino group is on the carbon adjacent to the carboxyl group.
Male sex hormones.
A reactive intermediate formed by b-elimination from adjacent carbon atoms of a benzene ring and having a triple bond in the benzene ring. The second p bond of the benzyne triple bond is formed by the weak overlap of coplanar 2p orbitals on adjacent carbons.
In a bicyclic system, the carbon atoms where the rings are fused together.
A unit of energy; it is the amount of energy needed to raise the temperature of 1 g of water by 1 °C from 14.5 °C to 15.5 °C. A related unit is the joule: 1 cal = 4.184 J. (Section 5.1)
An addition reaction in which a nucleophile and a proton are added across the two ends of a conjugated p system.
elimination (of radicals)
In radical reaction mechanisms, a step in which a bond forms between the alpha (a) and beta (b) positions. As a result, a single bond at the b position is cleaved, causing the compound to fragment into two pieces.
Protons that are not interchangeable by rotational symmetry but are interchangeable by reflectional symmetry.
A bond to a chair conformation of cyclohexane that extends from the ring roughly perpendicular to the imaginary axis through the center of the ring; a bond that lies roughly along the equator of a cyclohexane ring
A reaction in which the Gibbs free energy of the products is lower than that of the reactants. The position of equilibrium for an exergonic reaction favors products.
In mass spectrometry, when the molecular ion breaks apart into fragments.
CFCs that were heavily used for a wide variety of commercial applications, including as refrigerants, as propellants, in the production of foam insulation, as fire-fighting materials, and many other useful applications.
Gases in an atmosphere that absorb and emit infrared radiation (radiant heat), “trapping” heat in the atmosphere. (Section 18.2)
A catalyst that is in the same phase as the reactant substances. (Section 14.7)
A drawing style inwhich the electrons take center stage.linear polymer (Sect. 27.6): A polymer thathas only a minimal amount of branching or nobranching at all.
A method for building a peptide from protected building blocks.
A region of space that can hold two electrons
The amide linkage by which two amino acids are coupled together to form peptides.
The study of three-dimensional arrangements of atoms in molecules
The carbon atoms of a carbon-carbon double bond.
