What is the difference between organic and inorganic compound?

Answer 1

In general organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds.

Inorganic is everything else and generally do not contain carbon (with some exceptions).

Organic compounds contain carbon atoms bonded with other elements, typically hydrogen, oxygen, nitrogen, and sometimes sulfur. Inorganic compounds do not contain carbon-hydrogen bonds. Organic compounds are typically associated with living organisms, while inorganic compounds are often minerals or salts.
