Key Chemistry Terms and definitions covered in this textbook
  • atomic mass unit (amu)

    A unit based on the value of exactly 12 amu for the mass of the isotope of carbon that has six protons and six neutrons in the nucleus. (Sections 2.3 and 3.3)

  • atomic mass unit (amu).

    A mass exactly equal to 1 12th the mass of one carbon-12 atom. (3.1)

  • carbonyl group

    The C “O double bond, a characteristic feature of several organic functional groups, such as ketones and aldehydes. (Section 24.4)

  • cation

    A structure that bears a positive charge.

  • 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)

  • decomposition reaction

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

  • deuterium

    The isotope of hydrogen whose nucleus contains a proton and a neutron: 2 1H. (Section 22.2)

  • dimensional analysis

    A method of problem solving in which units are carried through all calculations. Dimensional analysis ensures that the final answer of a calculation has the desired units. (Section 1.6)

  • enantiomers

    Two mirror-image molecules of a chiral substance. The enantiomers are nonsuperimposable. (Section 23.4)

  • Glycoside

    A carbohydrate in which the !OH on its anomeric carbon is replaced by !OR

  • half-life

    The time required for the concentration of a reactant substance to decrease to half its initial value; the time required for half of a sample of a particular radioisotope to decay. (Sections 14.4 and 21.4)

  • half-reaction

    An equation for either an oxidation or a reduction that explicitly shows the electrons involved, for example, Zn2 + 1aq2 + 2 e- ¡ Zn1s2. (Section 20.2)

  • Hertz (Hz)

    The unit in which frequency is measured: s 21 (read “per second”).

  • Kelvin scale

    The absolute temperature scale; the SI unit for temperature is the kelvin. Zero on the Kelvin scale corresponds to -273.15 °C. (Section 1.4)

  • l-Monosaccharide

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

  • loss of a leaving group

    One of the four arrow-pushing patterns for ionic reactions.

  • Nucleophilic substitution

    Any reaction in which one nucleophile is substituted for another at a tetravalent carbon atom.

  • retro Diels-Alder reaction

    The reverse of a Diels-Alder reaction, achieved at high temperature. A cyclohexene derivative is converted into a diene and a dienophile.

  • solvolysis

    A substitution reaction in which the solvent functions as the nucleophile.

  • weak activators

    Groups that weakly activate an aromatic ring toward electrophilic aromatic substitution, thereby enhancing the rate of the reaction.
