Full solutions for Modern Chemistry: Student Edition 2012 | 1st Edition
The SI unit of radioactivity. It corresponds to one nuclear disintegration per second. (Section 21.4)
The cycle that relates lattice energies of ionic compounds to ionization energies, electron affinities, heats of sublimation and formation, and bond enthalpies. (9.3)
A process in a chemical reaction that occurs in a single step. An overall chemical reaction consists of one or more elementary reactions or steps. (Section 14.6)
A reaction that occurs between chlorobenzene and either NaOH (at high temperature) or NaNH2.
For a mixture containing two enantiomers, the difference between the percent concentration of the major enantiomer and the percent concentration of its mirror image.
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)
A cyclic ether containing a three-membered ring system. Also called an oxirane (also see Sect. 14.7).
A barbed curved arrow used to show the change in position of a single electron.
Fourier transform NMR (FT-NMR)
The modern NMR method that is based on a constant magnetic fi eld, a short pulse of electromagnetic radiation, and a mathematical Fourier transform to produce the spectrum
The equilibrium established between substances in two or more different phases, for example, between a gas and a solid or between a solid and a liquid. (Section 15.4)
A polar group that has favorable interactions with water.
A compound containing a five-membered ring that is similar to pyrrole but has one extra nitrogen atom at the 3 position.
A structure corresponding to a local minimum (valley) in an energy diagram.
isoelectric point (pI)
For an amino acid, the specific pH at which the concentration of the zwitterionic form reaches its maximum value.
A point in space where the value of a wave function is zero
Pauli exclusion principle
The rule that states that an atomic orbital or molecular orbital can accommodate a maximum of two electrons with opposite spin.
The positively charged intermediate of an electrophilic aromatic substitution reaction.
The threedimensional shape of a protein.
A signal of an NMR spectrum that is shifted toward the right (smaller chemical shift) on the chart paper.
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.
