3D Hydrocarbon Models – Alkanes, Alkenes, Alkynes, Benzene, and Br₂ Addition

ChemistryOrganic ChemistryAges 16–17

Ball-and-stick (or space-filling) models of methane, ethane, propane, butane, 2-methylpropane, ethylene, propene, acetylene, and benzene are built automatically with sp³/sp²/sp geometry; drag or touch to rotate. For alkenes and alkynes, click Add Br₂: the Br₂ molecule approaches the multiple bond, the π bond breaks open, one Br atom attaches to each carbon, and the bromine solution loses its color. Compare the C₄H₁₀ isomers side by side.
