Step-by-step explanation:
Carbon is a special element in chemistry. In other words, the chemistry of carbon is one of the most widely studied chemistry in the chemical science field. In fact, this branch is known as the carbon chemistry.
Carbon is a special element because of its ability to form covalent bonds. Not only that, it can form single or double bonds with elements like oxygen, hydrogen, nitrogen and sulfur. It is this ability to form multiple bonds and rings that carbon is useful in organic compounds.
