Organic chemistry is the branch of chemistry that deals with organic compounds’ structure, properties, and reactions. It constitutes the root of all earthly life. It tells us about natural product synthesis, polymers, drugs, and individual organic molecules.
Organic chemistry plays an integral role in our daily life. Organic compounds direct the preparation of numerous valuable products, such as agricultural chemicals, pharmaceuticals, food additives, paint, plastics, enzymes, cosmetics, etc.
