organic matters
compounds primarily made of carbon, hydrogen, and often oxygen, nitrogen, or other elements, that are found in living organisms.
Inorganic matters
compounds not primarily made of carbon, typically including minerals and metals, that do not originate from living organisms.
Saturated hydrocarbon
A type of hydrocarbon in which all carbon atoms are connected by single bonds, allowing the maximum number of hydrogen atoms to be attached.
Unsaturated hydrocarbon
A type of hydrocarbon that contains one or more double or triple bonds between carbon atoms, resulting in fewer hydrogen atoms than in saturated hydrocarbons.
