(1).Inorganic chemistry : The branch of chemistry which deals with the study of elements and compounds other than those of carbon,derived mainly from inanimate(non-living) objects,is
called inorganic chemistry.
(2). Organic chemistry:The branch of chemistry which deals with the study of carbon compounds mostly derived from animals and plant kingdom is called organic chemistry.
(3). Physical chemistry:The branch of chemistry which deals with the study of fundamental chemical phenomena is called physical chemical.
(4). Analytical chemistry:The branch of chemistry which deals with the detection and estimation of elements and compounds,which are found in nature or are synthesized in laboratories is called analytical chemistry.
(5). Biochemistry:The branch of chemistry which deals with the study of chemical changes taking place in the various life processes going on in living organism is called biochemistry.
(6). Pharmaceutical chemistry:The branch of chemistry which deals with the manufacture of drugs and medicines is called pharmaceutical chemistry.
(7). Industrial chemistry:The branch of chemistry which deals with the production of chemical species on a large scale is called industrial chemistry.It is also deals with the study of instruments required for the production of chemicals.

Importance of studying chemistry:Chemistry is playing a useful role directly or indirectly in the cultural,industrial and economic development in the modern fast developing society.
Some of the major contributions of this great science to modern living are given below:
(1). Improvement and maintanence of health:Chemistry is responsible for the discovery of a large number of drugs and medicines.This has helped in eradicating most of the diseases,improving health and increasing span of life.
(2). Agriculture: Chemistry has played a key role in producing fertilizers,compounds of nitrogen,phosphorus and potassium etc.,and insecticides( d.d.t., b.h.c. etc.).This has increased and improved the quality of food production.other contribution of chemistry is towards chemical preservatives and testing adulteration etc.
(3). Industry:Chemistry is playing an important role in a number of industries such as glass cement,textile,paper,paints,synthetic fibre,varnishes,building materials and electroplating etc.
(4). Warfare Chemistry has also increased the fighting power of man.Chemistry has helped in producing high power explosives such as t.n.t.,poisonous gases such as phosgene and thousands of other deadly weapons.The most modern weapons of human destruction like atom and hydrogen bombs are due to the joint efforts of chemists and physicists.
(5).Miscelleneous:Chemistry has made the modern homes safer,more comfortable and more beautiful by providing fire proof,water proof and sound proof materials etc.Chemistry has also played an important role in providing means of recreation and entertainment such as photographic films,grammophone records and cassettes etc.
