Definition of Chemistry 

Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter. It explores how substances interact, combine, and transform through chemical reactions. Chemistry plays a fundamental role in understanding natural phenomena and developing new materials, medicines, and technologies.

BRANCHES OF CHEMISTRY

The main branches of chemistry are:

1. Organic Chemistry – The study of carbon-containing compounds, including their structure, properties, reactions, and applications.
2. Inorganic Chemistry – Focuses on non-carbon compounds, including metals, minerals, and organometallic substances.
3. Physical Chemistry – Examines the principles of physics in chemical systems, including energy changes, reaction rates, and quantum mechanics.
4. Analytical Chemistry – Involves techniques and methods for identifying and quantifying substances in a sample.
5. Biochemistry – The study of chemical processes within living organisms, including metabolism, DNA, proteins, and enzymes.

Other specialized fields include Environmental Chemistry, Industrial Chemistry, Nuclear Chemistry, and Theoretical Chemistry.
