  • Walden inversion
  • Originally, a reaction sequence developed by Paul Walden whereby a chiral starting material was transformed to its enantiomer by a series of steroespecific reactions. Current usage is more general and refers to the inversion of configuration that attends any bimolecular nucleophilic substitution
  • Wave function
  • The solutions to the arithmetic expressions that express the energy of an electron in an atom
  • Wavelength
  • Distance between two successive maxima (peaks)or two successive minima (troughs) of a wave
  • Wavenumbers
  • Conventional units in infrared spectroscopy that are proportional to frequency. Wavenumbers are cited in reciprocal centimeters (cm-1)
  • Wax
  • A mixture of water-repellent substances that form a protective coating on the leaves of plants, the fur of animals, and the feathers of birds, among other things. A principal component of a wax is often an ester in which both the acyl portion and the alkyl portion are characterized by long carbon chains.
  • Weak acid
  • An acid that is weaker than H3O+
  • Weak base
  • A base that is weaker than HO-
  • Williamson ether synthesis
  • Method for the preparation of ether involving an SN2 reaction between an alkoxide ion and a primary alky halide FIG
  • Wittig reaction
  • Method for the synthesis of alkenes by the reaction of an aldehyde or a ketone with a phosphorus ylide. FIG
  • Wolff-Kishner reduction
  • Method for reducing the carbonyl group of aldehydes and ketones to a methylene group (C=O à CH2) by treatment with hydrazine (H2NNH2) and base (KOH) in a high-boiling alcohol solvent
  • Wood alcohol
  • A common name for methanol, CH3OH
