8.1 Introduction Alkenes are hydrocarbons whose molecules contain the carbon-carbon double bond. Hydrocarbons whose molecules contain the carbon-carbon triple bond are called alkynes

Arenes: Nomenclature Monosubstituted benzene derivatives are names as other hydrocarbons using the following set of rules: 1. Benzene is the parent name; when a benzene ring is a substituent on another chain, it is referred to as a \phenyl\ group
