BASIC INFORMATION ABOUT CHEMISTRY:-
CHEMISTRY AND ITS BRANCHES:-
The branch of science that studies the preparation, properties, structures and
reactions of various substances is called chemistry.
Chemistry has been divided into different branches based upon the specialised
field of study. Some of these are listed below:-
1. Physical Chemistry:- the branch of chemistry that deals with different
laws and theories as well as the relations between physical properties of
substances and their chemical composition and transformations.
2. Inorganic chemistry:- the branch of chemistry which deals with the
synthesis, structures, composition and behaviour of inorganic compounds.
This field covers all chemical compounds except the carbon based
compounds containing C-H bond.
3. Organic Chemistry:- The branch of chemistry that deals with the
structures, properties and reactions of organic compounds composed of
carbon and hydrogen and may contain some other elements.
4. Industrial chemistry:- The branch of chemistry that deals with the
chemistry involved in industrial procedures.
5. Biochemistry:- the branch of chemistry which deals with the structure
and behaviour of the components of cells and the chemical processes in
living organisms.
6. Analytical chemistry:- the branch of chemistry which deals with the
qualitative and quantitative analysis of different substances.
7. Nuclear Chemistry:- The branch of chemistry which deals with the
study of nuclear reactions such as fission and fusion, etc.
IMPORTANCE OF CHEMISTRY:-
Chemistry plays a very important role in our daily life and has wide range of
applications in different fields.
IMPORTANCE OF CHEMISTRY IN AGRICULTURE AND FOOD:-
• Chemical fertilisers such as urea, ammonium sulphate, calcium
superphosphate etc. are used for the better production of crops.
• To protect the crops from insects and harmful bacteria by the use of
insecticides, fungicides and pesticides such as DDT, gammaxene etc.
