Key Chemistry Terms and definitions covered in this textbook
  • acidic anhydride (acidic oxide)

    An oxide that forms an acid when added to water; soluble nonmetal oxides are acidic anhydrides. (Section 22.5)

  • alditol

    The product obtained when the aldehyde group of an aldose is reduced.

  • anode.

    The electrode at which oxidation occurs. (18.2)

  • Boyle’s law.

    The volume of a fixed amount of gas maintained at constant temperature is inversely proportional to the gas pressure. (5.3)

  • chair conformation

    The lowest energy conformation for cyclohexane, in which all bond angles are fairly close to 109.5° and all hydrogen atoms are staggered.

  • chromophore

    In UV-Vis spectroscopy, the region of the molecule responsible for the absorption (the conjugated p system).

  • crystal-field theory

    A theory that accounts for the colors and the magnetic and other properties of transition-metal complexes in terms of the splitting of the energies of metal ion d orbitals by the electrostatic interaction with the ligands. (Section 23.6)

  • delocalization

    The spreading of a charge or lone pair as described by resonance theory.

  • dilution.

    A procedure for preparing a less concentrated solution from a more concentrated solution. (4.5)

  • first-order reaction

    A reaction in which the reaction rate is proportional to the concentration of a single reactant, raised to the first power. (Section 14.4)

  • Glass transition temperature (TG)

    The temperature at which a polymer undergoes the transition from a hard glass to a rubbery state

  • Haloalkane (alkyl halide)

    A compound containing a halogen atom covalently bonded to an sp3 -hybridized carbon atom. Given the symbol R!X.

  • limiting reactant (limiting reagent)

    The reactant present in the smallest stoichiometric quantity in a mixture of reactants; the amount of product that can form is limited by the complete consumption of the limiting reactant. (Section 3.7)

  • molecular compound

    A compound that consists of molecules. (Section 2.6)

  • Nucleophilicity

    A kinetic property measured by the rate at which a nucleophile causes nucleophilic substitution on a reference compound under a standardized set of experimental conditions.

  • Phenyl group

    A group derived by removing an H from benzene; abbreviated C6H5! or Ph!.

  • Photons

    An alternative way to describe electromagnetic radiation as a stream of particles

  • polysaccharides

    Polymers made up of repeating monosaccharide units linked together by glycoside bonds.

  • Raoult’s law

    A law stating that the partial pressure of a solvent over a solution, Psolution, is given by the vapor pressure of the pure solvent, P° solvent, times the mole fraction of a solvent in the solution, Xsolvent: Psolution = XsolventP° solvent. (Section 13.5)

  • Steric hindrance

    The ability of groups, because of their size, to hinder access to a reaction site within a molecule.
