1. HalogenoalkanesHalogenoalkanes are a homologous series with the general formula CnH2n+1X where X is F, Cl, Br or I.
2. Reactivity of HalogenoalkanesThe C-Halogen (C-X) bond is polar.
3. Nucleophilic Substitution - HydrolysisThe addition of water can be used to break a bond and split a molecule into 2 products.
4. Reaction with AmmoniaThe reaction of halogenoalkanes with ammonia is a nucleophilic substitution.
5. EliminationWhen a halogenoalkane is heated with ethanolic sodium or potassium hydroxide the OH- acts as a base rather than as a nucleophile.
6. Organohalogen compounds and the EnvironmentThe ozone layer is found 10 - 40km above the earth's surface in the outer stratosphere.
