Hydrocarbons that contain one or more carbon-carbon triple bonds. They have the general formula CnH2n22, where n 5 2,3, . . . . (24.2)
A conformation in which a hydrogen atom and a leaving group are separated by a dihedral angle of exactly 180°.
An elementary step that involves two molecules. (13.5)
A copolymer in which the different homopolymer subunits are connected together in one chain.
An ion with a net positive charge. (2.5)
In NMR spectroscopy, protons (or carbon atoms) that occupy identical electronic environments and produce only one signal.
Fourier-transform NMR (FT-NMR)
In nuclear magnetic resonance (NMR) spectroscopy, a technique in which the sample is irradiated with a short pulse that covers the entire range of relevant rf frequencies.
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.
A series of atoms, ions, or molecules having the same number of electrons. (Section 7.3)
An ion or molecule that coordinates to a metal atom or to a metal ion to form a complex. (Section 23.2)
A compound that possesses chirality centers and an internal plane of symmetry.
A biopolymer formed from amino acids. (Section 24.7)
A chemical entity with an unpaired electron.
A carbohydrate that is oxidized upon treatment with Tollens’ reagent, Fehling’s reagent, or Benedict’s reagent.
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 region of space around a nucleus that can be occupied by electrons, corresponding to a principal quantum number
solubility-product constant (solubility product)1Ksp2
An equilibrium constant related to the equilibrium between a solid salt and its ions in solution. It provides a quantitative measure of the solubility of a slightly soluble salt. (Section 17.4)
Fibrous proteins that are used for their structural rigidity. Examples include a-keratins found in hair, nails, skin, feathers, and wool.
An addition reaction in which two groups are added to the same face of a p bond.
Cleavage by heating
