What element is found in all organic molecules?

The answer is Carbon

Explanation:

Organic compounds are considered to be all those chemical substances that contain some carbon atom in their molecule. Besides carbon, hydrogen is an important element in its constitution.

Carbon molecules unite with each other very easily, developing basic skeletons in all organic compounds. These chains can have different lengths and shapes.

Each carbon atom has a valence of 4 and the bonds in organic compounds are covalent, with the possibility of double or triple bonds.

Organic compounds can also contain other types of chemical elements other than carbon (oxygen, nitrogen, sulfur, etc.) called functional groups. A wide variety of organic compounds are formed from these functional groups.
