Key Chemistry Terms and definitions covered in this textbook
  • Acetal

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

  • bimolecular

    For mechanisms, a step that involves two chemical entities.

  • boiling-point elevation (DTb).

    The boiling point of the solution (Tb) minus the boiling point of the pure solvent (T° b). (12.6)

  • chemical properties

    Properties that describe a substance’s composition and its reactivity; how the substance reacts or changes into other substances. (Section 1.3)

  • chemical reactions

    Processes in which one or more substances are converted into other substances; also called chemical changes. (Section 1.3)

  • Crown ether

    A cyclic polyether derived from ethylene glycol and substituted ethylene glycols.

  • Downfield

    A signal of an NMR spectrum that is shifted toward the left (larger chemical shift) on the chart paper.

  • electrometallurgy

    The use of electrolysis to reduce or refine metals. (Section 20.9)

  • entropy

    A thermodynamic function associated with the number of different equivalent energy states or spatial arrangements in which a system may be found. It is a thermodynamic state function, which means that once we specify the conditions for a system—that is, the temperature, pressure, and so on—the entropy is defined. (Section 19.2)

  • fracking

    The practice in which water laden with sand and other materials is pumped at high pressure into rock formations to release natural gas and other petroleum materials. (Section 18.4)

  • lattice energy

    The energy required to separate completely the ions in an ionic solid. (Section 8.2)

  • mass spectrometer

    An instrument used to measure the precise masses and relative amounts of atomic and molecular ions. (Section 2.4)

  • mass spectrometry

    The study ofthe interaction between matter and an energysource other than electromagnetic radiation. Massspectrometry is used primarily to determine the molecular weight and molecular formula of a compound.

  • Micelle

    A spherical arrangement of organic molecules in water solution clustered so that their hydrophobic parts are buried inside the sphere and their hydrophilic parts are on the surface of the sphere and in contact with water

  • mineral

    A solid, inorganic substance occurring in nature, such as calcium carbonate, which occurs as calcite. (Section 23.1)

  • molal boiling-point-elevation constant (Kb)

    A constant characteristic of a particular solvent that gives the increase in boiling point as a function of solution molality: ?Tb = Kbm. (Section 13.5)

  • phenoxide

    The conjugate base of phenol or a substituted phenol.

  • Ribosomal RNA (rRNA)

    A ribonucleic acid found in ribosomes, the sites of protein synthesi

  • thermosetting resins

    Highly crosslinked polymers that are generally very hard and insoluble.

  • twist boat

    A conformation of cyclohexane that is lower in energy than a boat conformation but higher in energy than a chair conformation.
