About Nomenclature, Structure and Reactivity
Alkyl halides are named by selecting the longest carbon chain and locating the halogen substituent, while their structures are classified as primary, secondary or tertiary. Their reactivity includes nucleophilic substitution and elimination, with the behaviour of leaving groups and the distinction between SN1 and SN2 mechanisms linked to substrate structure.
