A thermodynamic function associated with the number of different equivalent energy states or spatial arrangements in which a system may be found. It is a thermodynamic state function, which means that once we specify the conditions for a system—that is, the temperature, pressure, and so on—the entropy is defined. (Section 19.2)
Important biological molecules that catalyze virtually all cellular processes.
A higher energy state than the ground state. (Section 6.3)
An atom or group of atoms within a molecule that shows a characteristic set of physical and chemical properties
A form of isomerism in which compounds with the same type and number of atoms and the same chemical bonds have different spatial arrangements of these atoms and bonds. (Sections 23.4 and 24.4)
A lithium dialkyl cuprate (R2CuLi).
A compound containing a hydroxyl group (OH) and an alkoxy group (OR) connected to the same carbon atom.
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 compound thatrotates plane-polarized light in a counterclockwisedirection (-).
Elements that lie along the diagonal line separating the metals from the nonmetals in the periodic table; the properties of metalloids are intermediate between those of metals and nonmetals. (Section 2.5)
A collection of Avogadro’s number 16.022 * 10232 of objects; for example, a mole of H2O is 6.022 * 1023 H2O molecules. (Section 3.4)
nuclear disintegration series
A series of nuclear reactions that begins with an unstable nucleus and terminates with a stable one; also called a radioactive series. (Section 21.2)
A conversion of one kind of nucleus to another. (Section 21.3)
Changes (such as a phase change) that occur with no change in chemical composition. (Section 1.3)
For light, the orientation of the electric field.
probability density 1c22
A value that represents the probability that an electron will be found at a given point in space. Also called electron density. (Section 6.5)
A positively charged subatomic particle found in the nucleus of an atom. (Section 2.3)
The power to which the concentration of a reactant is raised in a rate law. (Section 14.3)
The manner in which a protein is coiled or stretched. (Section 24.7)
In radical reactions, a step in which two radicals are joined to give a compound with no unshared electrons.
