Organic molecules all contain carbon, often in chains or rings. They also contain hydrogen. I can't think of any other properties common to all organic molecules. Organic substances tend to be volatile, many are combustible, and many have odours.

Anhydrite is a mineral composed of calcium, sulfur, and oxygen. It does not contain any water molecules in its structure, which differentiates it from gypsum, another common calcium sulfate mineral that does contain water molecules.
The formula for ethane is C2H6, and the formula for ethylene is C2H4. Both molecules contain two carbon atoms.
