- 2-methylbutane is a hydrocarbon because it only contains carbon and hydrogen atoms.
- Benzene is a hydrocarbon with a ring structure made up of carbon atoms and hydrogen atoms.
- Cyclohexane is also a hydrocarbon with a ring structure made up of carbon atoms and hydrogen atoms.
Methylpropanoate, on the other hand, contains carbon, hydrogen, and oxygen atoms, which means it is not a hydrocarbon.
