* Five traditional areas of study are organic chemistry, inorganic chemistry, biochemistry, analytical chemistry, and physical chemistry. * Organic chemistry- defined as the studies of all the chemicals containing carbon * Inorganic chemistry- defined as the studies of all the chemicals that do not contain carbon * Biochemistry- is the study of the processes that take place in organisms * Analytical chemistry- is the area of study that focuses on the composition of matter * Physical chemistry- area that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change C. Pure and Applied Chemistry
* Pure chemistry- is the pursuit of chemical knowledge for its own sake * Applied chemistry- is the research that directed toward a practical goal or application * Pure research can lead to an application, but an application can exist before research is done to explain how it works 1. Nylon
