Hydrocarbon

Deutsch: Kohlenwasserstoff / Español: Hidrocarburo / Português: Hidrocarboneto / Français: Hydrocarbure / Italiano: Idrocarburi
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.[1] Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls.[2] 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.

Hydrocarbon Mixture

Deutsch: Kohlenwasserstoffgemisch / Español: Mezcla de Hidrocarburos / Português: Mistura de Hidrocarbonetos / Français: Mélange d'Hydrocarbures / Italiano: Miscela di Idrocarburi

A hydrocarbon mixture in the environmental context refers to a blend of various organic compounds primarily composed of carbon (C) and hydrogen (H) atoms. These mixtures can be of natural origin (e.g., crude oil, natural gas) or result from human activities (e.g., solvents, fuels, lubricants). Their environmental relevance stems from their potential impacts on air, water, soil, and living organisms.
