Summary Introduction
Introduction:
Organic molecules are the compounds which contains carbon (as a form of ring or long chain), hydrogen, oxygen, and nitrogen in its structure. Certain organic compounds may also contain sulfur and phosphorus in its structure. But, the compounds which do not have carbon in its structure are called inorganic molecules.
