Organic Chemistry

Organic chemistry studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding. Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and theoretically.
