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
