1,2adduct
The product obtainedfrom 1,2addition across a conjugated p system.

Acetal
A molecule containing two !OR or !OAr groups bonded to the same carbon

angle strain
The increase in energy associated with a bond angle that has deviated from the preferred angle of 109.5°.

aromatic hydrocarbons
Hydrocarbon compounds that contain a planar, cyclic arrangement of carbon atoms linked by both s and delocalized p bonds. (Section 24.2)

base
A substance that is an H+ acceptor; a base produces an excess of OH1aq2 ions when it dissolves in water. (Section 4.3)

bodycentered lattice
A crystal lattice in which the lattice points are located at the center and corners of each unit cell. (Section 12.2)

chaingrowth polymer
A polymer that is formed under conditions in which the monomers do not react directly with each other, but rather, each monomer is added to the growing chain, one at a time.

charcoal
A form of carbon produced when wood is heated strongly in a deficiency of air. (Section 22.9)

diastereotopic
Nonequivalent protons for which the replacement test produces diastereomers.

dihydroxylation
A reaction characterized by the addition of two hydroxyl groups (OH) across an alkene.

Exothermic reaction
A reaction in which the enthalpy of the products is lower than that of the reactants; a reaction in which heat is released.

heat of combustion
The heat given off during a reaction in which an alkane reacts with oxygen to produce CO2 and water.

heterogeneous alloy
An alloy in which the components are not distributed uniformly; instead, two or more distinct phases with characteristic compositions are present. (Section 12.3)

intermetallic compound
A homogeneous alloy with definite properties and a fixed composition. Intermetallic compounds are stoichiometric compounds that form between metallic elements. (Section 12.3)

joule (J)
The SI unit of energy, 1 kg@m2 >s2. A related unit is the calorie: 4.184 J = 1 cal. (Section 5.1)

lMonosaccharide
A monosaccharide that, when written as a Fischer projection, has the !OH on its penultimate carbon to the left.

N terminus
For a peptide chain,the end that contains the amino group.

phenolate
The conjugate base of phenol or a substituted phenol.

photoelectric effect
The emission of electrons from a metal surface induced by light. (Section 6.2)

polar covalent bond
A covalent bond in which the electrons are not shared equally. (Section 8.4)
