Key Chemistry Terms and definitions covered in this textbook
  • acylium ion

    The resonancestabilized, cationic intermediate of a Friedel-Crafts acylation, formed by treating an acyl halide with aluminum trichloride.

  • Avogadro‚Äôs law.

    At constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of the gas present. (5.3)

  • base ionization constant (Kb).

    The equilibrium constant for the base ionization. (15.6)

  • bond enthalpy

    The enthalpy change, ?H, required to break a particular bond when the substance is in the gas phase. (Section 8.8)

  • calorimetry

    The experimental measurement of heat produced in chemical and physical processes. (Section 5.5)

  • collision model

    A model of reaction rates based on the idea that molecules must collide to react; it explains the factors influencing reaction rates in terms of the frequency of collisions, the number of collisions with energies exceeding the activation energy, and the probability that the collisions occur with suitable orientations. (Section 14.5)

  • column chromatography

    A technique by which compounds are separated from each other based on a difference in the way they interact with the medium (the adsorbent) through which they are passed.

  • conjugate base

    In an acid-base reaction, the product that results when an acid is deprotonated.

  • Diazonium ion

    An ArN2 1 or RN2 1 ion

  • diffusion

    The spreading of one substance through a space occupied by one or more other substances. (Section 10.8)

  • Enantiomers

    Stereoisomers that are nonsuperposable mirror images of each other; refers to a relationship between pairs of objects

  • gamma radiation

    Energetic electromagnetic radiation emanating from the nucleus of a radioactive atom. (Section 21.1)

  • glass transition temperature (Tg)

    The temperature at which noncrystalline polymers become very soft.

  • Henderson-Hasselbalch equation

    An equation that is often employed to calculate the pH of buffered solutions: pH = pKa + log 3conjugated base4 3acid4

  • Ligand

    A Lewis base bonded to a metal atom in a coordination compound. It may bond strongly or weakly.

  • oxyacid

    A compound in which one or more OH groups, and possibly additional oxygen atoms, are bonded to a central atom. (Section 16.10)

  • Pericyclic reaction

    A reaction that takes place in a single step, without intermediates, and involves a cyclic redistribution of bonding electrons

  • periodic table

    The arrangement of elements in order of increasing atomic number, with elements having similar properties placed in vertical columns. (Section 2.5)

  • pi (p) bond

    A bond formed from adjacent, overlapping p orbitals.

  • step-growth polymers

    Polymers that are formed under conditions in which the individual monomers react with each other to form oligomers, which are then joined together to form polymers.
