alpha (a) position
The position immediately adjacent to a functional group.
An organic compound that has an NR2 group attached to a carbonyl. (Section 24.4)
A liquid mixture of constant composition with a boiling point that is different from that of any of its components.
A copolymer in which the different homopolymer subunits are connected together in one chain.
The cycle that relates lattice energies of ionic compounds to ionization energies, electron affinities, heats of sublimation and formation, and bond enthalpies. (9.3)
The heating of an ore to bring about its decomposition and the elimination of a volatile product. For example, a carbonate ore might be calcined to drive off CO2. (Section 23.2)
Energy added or released when an electron is added to an atom or molecule.
A charge associated with any atom that does not exhibit the appropriate number of valence electrons.
The lowest-energy, or most stable, state. (Section 6.3)
Compounds whose molecules have the same overall composition but different structures. (Sections 2.9 and 23.4)
A device inwhich a compound is first vaporized and convertedinto ions, which are then separated anddetected.
nucleophilic acyl substitution
A reaction in which a nucleophile attacks a carboxylic acid derivative.
The smallest increment (a quantum) of radiant energy; a photon of light with frequency n has an energy equal to hn. (Section 6.2)
A polyester in which the carboxyl groups are derived from carbonic acid
A biopolymer formed from amino acids. (Section 24.7)
A reaction that obeys conservation of orbital symmetry.
van der Waals forces
A group of intermolecular attractive forces including dipole-dipole, dipole-induced dipole, and induced dipole-induced dipole (dispersion) forces
A carbocation in which the positive charge resides on a vinylic carbon atom. This type of carbocation is very unstable and will not readily form in most cases.
A reaction that converts an aldehyde or ketone into an alkene, with the introduction of one or more carbon atoms.
