Reactions
  • Substitution by hydroxide:

The haloalkane undergoes simple substitution to change into an alcohol. This reaction occurs with alkalis in aqueous solution:
  • Elimination by hydroxide:

A water molecule is eliminated when alkalis in ethanolic solution are added to haloalkanes: . An alkene is formed.
  • Silver nitrate:

An alkali is first added, to convert the haloalkane into an alcohol and the ion in solution. Then silver nitrate is added...
