Key Chemistry Terms and definitions covered in this textbook
  • absolute temperature scale.

    A temperature scale that uses the absolute zero of temperature as the lowest temperature. (5.3)

  • addition reactions

    Reactions that are characterized by the addition of two groups across a double bond. In the process, the pi (p) bond is broken.

  • alkyl halide

    An organic compound containing at least one halogen.

  • amorphous solid

    A solid whose molecular arrangement lacks the regularly repeating long- range pattern of a crystal. (Section 12.2)

  • amphoteric

    Compounds that will react with either acids or bases. Amino acids are amphoteric.

  • Aufbau principle

    Orbitals fi ll in order of increasing energy, from lowest to highest.

  • Base peak

    The peak caused by the most abundant ion in a mass spectrum; the most intense peak. It is assigned an arbitrary intensity of 100

  • bond enthalpy

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

  • dipole moment (m)

    The amount of partial charge (d ) on either end of a dipole multiplied by the distance of separation (d): m=d × d

  • extensive property

    A property that depends on the amount of material considered; for example, mass or volume. (Section 1.3)

  • Frost circles

    A simple method for drawing the relative energy levels of the MOs for a ring assembled from continuously overlapping p orbitals.

  • heterocycle

    A cyclic compound containing at least one heteroatom (such as S, N, or O) in the ring.

  • Homolytic bond cleavage

    Cleavage of a bond so that each fragment retains one electron; formation of radicals.

  • law of constant composition

    A law that states that the elemental composition of a pure compound is always the same, regardless of its source; also called the law of definite proportions. (Section 1.2)

  • nucleophilic aromatic substitution

    A substitution reaction in which an aromatic ring is attacked by a nucleophile, which replaces a leaving group.

  • pi 1P2 molecular orbital

    A molecular orbital that concentrates the electron density on opposite sides of an imaginary line that passes through the nuclei. (Section 9.8)

  • Polypeptide

    A macromolecule containing many amino acid units, each joined to the next by a peptide bond

  • Shielding in NMR

    Also called diamagnetic shielding; the term refers to the reduction in magnetic fi eld strength experienced by a nucleus underneath electron density induced to circulate when the molecule is placed in a strong magnetic fi eld.

  • silica

    Common name for silicon dioxide. (Section 22.4)

  • Thiol

    A compound containing an !SH (sulfhydryl) group bonded to an sp3 -hybridized carbon.
