Why do alkenes react?
Alkenes are unsaturated hydrocarbons that contain a carbon-carbon double bond (C=C). This double bond consists of a standard single bond (a sigma bond) and a second bond (a pi bond) where the electrons are spread out above and below the plane of the atoms.
Step-by-step lessons on AQA A Level Chemistry Addition reactions of alkenes. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
