CHAPTER 16: Halogen Derivatives

CHAPTER 16: Halogen  Derivatives

  • Introduction to Halogenoalkanes
  • Reactions of Halogenoalkanes
  • Uses of Halogenoalkanes

Learning outcomes:

 

  • recall the chemistry of halogenoalkanes as exemplified by
    • the following nucleophilic substitution reactions of bromoethane: hydrolysis, formation of nitriles, formation of primary amines by reaction with ammonia
    • the elimination of hydrogen bromide from 2-bromopropane.
  • describe the mechanism of nucleophilic substitution (by both SN1 and SN2 mechanisms) in halogenoalkanes.
  • interpret the different reactivities of halogenoalkanes(with particular reference to hydrolysis and to the relative strengths of the C-Hal bonds).
  • explain the uses of fluoroalkanes and fluorohalogenoalkanes in terms of their relative chemical inertness.
  • recognise the concern about the effect of chlorofluoroalkanes on the ozone layer
