chemists must design strategies to synthesize these drugs from relatively simple stating material; Scope of Chemistry Chemists work in all these areas. Modern technology calls for new materials with unusual properties; chemists must devise methods of producing these materials; Modern medicine needs drugs to perform specific tasks in the human body;
