infoWhy this? Replacing a hydrogen atom in an alkane with a halogen introduces a polar carbon–halogen bond whose reactions can be explained through nucleophilic substitution and elimination. These transformations show how functional groups enable the preparation of new organic compounds.

scheduleWhy now? Knowledge of alkanes, bond polarity, and reaction mechanisms provides the basis for explaining the reactivity of halogenoalkanes. Their substitution and elimination reactions also introduce routes to the alcohols and alkenes studied next.
