Alkenes
Bayani Gaba-gaba
While alkanes are the backbone of fuels, alkenes are the backbone of the chemical industry. Their carbon-carbon double bond makes them far more reactive, and this reactivity is what allows chemists to build plastics, make ethanol, and create countless everyday materials.
In this lesson you will learn the general formula for alkenes, why they are called unsaturated hydrocarbons, how to draw and name them, and how the bromine water test distinguishes them from alkanes.
Manufura
- Know that alkenes contain the functional group C=C
- Know the general formula for alkenes
- Explain why alkenes are classified as unsaturated hydrocarbons
- Understand how to draw the structural and displayed formulae for alkenes with up to four carbon atoms in the molecule, and name the unbranched-chain isomers
- Describe how bromine water can be used to distinguish between an alkane and an alkene
