In NMR spectroscopy, protons (or carbon atoms) that occupy identical electronic environments and produce only one signal.
A compound inwhich two carbon-carbon p bonds are separated from each other by exactly one s bond.
Compounds with the same molecular formula but a different connectivity of their atoms
The metal ion and its surrounding ligands. (Section 23.2)
The highest temperature at which it is possible to convert the gaseous form of a substance to a liquid. The critical temperature increases with an increase in the magnitude of intermolecular forces. (Section 11.4)
enthalpy of reaction
The enthalpy change associated with a chemical reaction. (Section 5.4)
Diastereomers that differ from each other in the configuration of only one chirality center.
frequency factor (A)
A term in the Arrhenius equation that is related to the frequency of collision and the probability that the collisions are favorably oriented for reaction. (Section 14.5)
Haloarene (aryl halide)
A compound containing a halogen atom bonded to a benzene ring. Given the symbol Ar!X
High-resolution mass spectrometry
Instrumentation that is capable of separating ions that differ in mass by as little as 0.0001 amu
A reaction for which the product distribution is determined by the relative rates at which the products are formed.
mean free path
The average distance traveled by a gas molecule between collisions. (Section 10.8)
A group of molecules arranged in a sphere such that the surface of the sphere is comprised of polar groups, rendering the micelle water soluble.
A spherical arrangement of organic molecules in water solution clustered so that their hydrophobic parts are buried inside the sphere and their hydrophilic parts are on the surface of the sphere and in contact with water
The net movement of solvent through a semipermeable membrane toward the solution with greater solute concentration. (Section 13.5)
A property that a substance possesses if it contains one or more unpaired electrons. A paramagnetic substance is drawn into a magnetic field. (Section 9.8)
A reaction that involves the participation of ions as reactants, intermediates, or products.
The stabilization associated with the delocalization of electrons via resonance.
sigma (s) bond
A bond that is characterized by circular symmetry with respect to the bond axis.
Sigma (s) molecular orbital
A molecular orbital in which electron density is concentrated between two nuclei, along the axis joining them, and is cylindrically symmetrical
