This is an overview of Topic 18: Haloalkanes. It includes nucleophilic substitution mechanism, hydrolysis, organohalogens and the ozone layer.
Hydrolysis of Haloalkanes
This video looks at the hydrolysis of haloalkanes using hot aqueous hydroxide ions or water and also displays nucleophilic substitution mechanism for the reaction.
Relative Rates of Hydrolysis of Haloakanes
This video describes the method used for the hydrolysis of haloalkanes and explains the trend down group 7 in terms of the relative rate of hydrolysis.
Organohalogens and the Ozone Layer
This video highlights the importance of the ozone layer and how it is destroyed by organohalogens.It also outlines ways scientists are trying to combat ozone depletion.
