Detailed explanation-1: -An organic compound is a member of a class of chemicals containing carbon atoms bound to one another and other atoms by covalent bonds and found in the cells of living organisms. Hydrogen, oxygen and nitrogen are typical elements which, in addition to carbon, make up organic compounds.

Detailed explanation-2: -Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds.

Detailed explanation-3: -The six most common atoms in organic molecules are C, H, O, N, P, and S. These six elements are the most abundant element in cells, thus they are called macronutrients. C, N, O, and H are the most abundant molecules which are required for the production of biomolecules like proteins, lipids etc.

Detailed explanation-4: -Although all organic compounds contain carbon, and almost all have hydrogen, most of them contain other elements as well. The most common other elements in organic compounds are oxygen, nitrogen, sulfur, and the halogens.

Detailed explanation-5: -Organic compounds essential to human functioning include carbohydrates, lipids, proteins, and nucleotides. These compounds are said to be organic because they contain both carbon and hydrogen.
