• compounds with the same chemical
  • The experimental work on the hydrolysis of 1,1-dichloroethane, which yielded glycol, and the chlorination of acetaldehyde giving 1,2-dichloroethane provided a good starting point for the development of the theory of the constitution of compounds with the same chemical formula, but different bond structure.

  • cobalt
  • He showed, among other things, that the formulas of many cobalt(III) and chromium(III) compounds can be understood if the metal has six ligands in an octahedral geometry. (wikipedia.org)
  • absolute
  • It is not to be confused with E - Z isomerism , which is an absolute stereochemical description, and only to be used with alkenes. (wikipedia.org)
