A self-contained electrochemical power source that contains one or more voltaic cells. (Section 20.7)
A compound containing a Br group and a hydroxyl group (OH) on adjacent carbon atoms.
In electrocyclic reactions,a type of rotation in which the orbitals being used to form the new s bond must rotate in the same way.
critical temperature (Tc).
The temperature above which a gas will not liquefy. (11.8)
An ionic compound that is formed upon treatment of a primary amine with NaNO2 and HCl.
In Diels-Alder reactions that produce bicyclic structures, the positions that are syn to the larger bridge.
Members of group 7A in the periodic table. (Section 7.8)
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)
Hückel criteria for aromaticity
To be aromatic, a monocyclic compound must have one 2p orbital on each atom of the ring, be planar or nearly so, and have (4n 1 2) p electrons in the cyclic arrangement of 2p orbitals
A solution that obeys Raoult’s law. (Section 13.5)
A substance that exhibits one or more partially ordered liquid phases above the melting point of the solid form. By contrast, in nonliquid crystalline substances the liquid phase that forms upon melting is completely unordered. (Section 11.7)
plane of symmetry
A plane that bisects a compound into two halves that are mirror images of each other.
A polymer constructed from nucleotides linked together.
Replacing this hydrogen by deuterium gives a chiral center with an R confi guration
An equation that relates the reaction rate to the concentrations of reactants (and sometimes of products also). (Section 14.3)
reaction quotient (Q)
The value that is obtained when concentrations of reactants and products are inserted into the equilibrium expression. If the concentrations are equilibrium concentrations, Q = K; otherwise, Q ? K. (Section 15.6)
Common name for silicon dioxide. (Section 22.4)
A polymer that can be molded when it is fi rst prepared, but once cooled, hardens irreversibly and cannot be remelted.
A conformation of cyclohexane that is lower in energy than a boat conformation but higher in energy than a chair conformation.
A compound containingone or more p bonds.
