Hydrocarbons
Hydrocarbons are molecules made up of only hydrogen and carbon atoms. A hydrocarbon's size affects its properties.
Hydrocarbons
- Hydrocarbons are molecules made up of only hydrogen and carbon atoms.
- Hydrocarbons differ in their size, which can change the properties of the hydrocarbon.
Boiling point
- Hydrocarbons with longer chains have higher boiling points.
Viscosity
- Hydrocarbons with longer chains have higher viscosity (i.e. they are thicker and flow less easily).
Flammability
- Hydrocarbons with longer chains are less flammable.
