A hydrocarbon is defined as?

Explanation:
Hydrocarbons are molecules made only from carbon and hydrogen, connected by covalent bonds. This means the substance contains no other elements like oxygen or nitrogen. That exact description matches the idea that the molecule has only hydrogen and carbon atoms covalently bonded. If a molecule includes oxygen or nitrogen, it isn’t a hydrocarbon, and a molecule made only of carbon isn’t a hydrocarbon because it lacks hydrogen.
