actual yield.
The amount of product actually obtained in a reaction. (3.10)

Avogadro’s law
A statement that the volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas. (Section 10.3)

bent
A type of geometry resulting from an sp3hybridized atom that has two lone pairs. For example, the oxygen atom in H2O.

Claisen condensation
A nucleophilic acyl substitution reaction in which the nucleophile is an ester enolate and the electrophile is an ester.

Confi guration
Refers to the arrangement of atoms about a stereocenter

decomposition reaction
A chemical reaction in which a single compound reacts to give two or more products. (Section 3.2)

Fischer projections
A drawing style that is often used when dealing with compounds bearing multiple chirality centers, especially for carbohydrates. (See also Sect. 5.7.)

heat capacity
The quantity of heat required to raise the temperature of a sample of matter by 1 °C (or 1 K). (Section 5.5)

Hyperconjugation
Interaction of electrons in a sbonding orbital with the vacant 2p orbital of an adjacent positively charged carbon.

isotactic
A polymer in which the repeating units contain chirality centers which all have the same configuration.

lanthanide contraction
The gradual decrease in atomic and ionic radii with increasing atomic number among the lanthanide elements, atomic numbers 57 through 70. The decrease arises because of a gradual increase in effective nuclear charge through the lanthanide series. (Section 23.1)

Node
A point in space where the value of a wave function is zero

oxonium ion
An intermediate with a positively charged oxygen atom.

oxyanion
A polyatomic anion that contains one or more oxygen atoms. (Section 2.8)

ozone
The name given to O3, an allotrope of oxygen. (Section 7.8)

plastic
A material that can be formed into particular shapes by application of heat and pressure. (Section 12.8)

precipitate
An insoluble substance that forms in, and separates from, a solution. (Section 4.2)

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)

spontaneous process
A process that is capable of proceeding in a given direction, as written or described, without needing to be driven by an outside source of energy. A process may be spontaneous even though it is very slow. (Section 19.1)

Zaitsev’s rule
A rule stating that the major product of a belimination reaction is the most stable alkene; that is, it is the alkene with the greatest number of substituents on the carboncarbon double bond
