What do you mean by hydrocarbon?

The word 'hydrocarbon' means an organic compound containing only carbon and hydrogen.

The term hydrocarbon refers to the simplest organic compounds containing only carbon and hydrogen. The majority of hydrocarbons found naturally occur in crude oil. Alkanes, alkenes and alkyne based compounds are different types of hydrocarbons.

Aromatic hydrocarbons (arenes), alkanes, alkenes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons. The majority of hydrocarbons found on earth naturally occur in crude oil, where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded, can catenate to form seemingly limitless chains.
