2 x 1 hour lessons

This module explores the chemistry of haloalkanes — organic compounds containing carbon–halogen bonds. You’ll learn how their reactivity is influenced by the polarity and strength of the C–X bond and how this leads to nucleophilic substitution reactions.

You’ll examine key reactions of haloalkanes with hydroxide ions, water, cyanide ions, and ammonia, gaining an understanding of the mechanisms and conditions required. The module also covers the environmental impact of haloalkanes, particularly their role in ozone layer depletion.

By the end of this module, you’ll be able to:

• Describe the structure and properties of haloalkanes

• Explain how the C–X bond influences reactivity

• Outline and interpret nucleophilic substitution mechanisms

• Write balanced equations for key reactions of haloalkanes

• Understand the environmental effects of CFCs and related compounds
