Physical Chemistry

Physical chemistry is one of the most important chemistry main topics that combines physics and chemistry. It deals with thermodynamics, chemical kinetics, electrochemistry, surface chemistry, and the study of solutions. This branch explains how and why chemical reactions occur and how energy changes during chemical processes.Chemistry LibreTexts.

Organic Chemistry

Organic chemistry focuses on carbon-containing compounds such as hydrocarbons, alcohols, ethers, aldehydes, ketones, carboxylic acids, polymers, and biomolecules. It forms the backbone of pharmaceuticals, petrochemicals, plastics, dyes, and synthetic fibers.

Inorganic Chemistry

Inorganic chemistry deals with elements and compounds other than most carbon-based compounds. Topics include atomic structure, periodic table trends, coordination compounds, metallurgy, acids, bases, and salts. This branch is essential for understanding materials, catalysts, and metal extraction.

Environmental Chemistry

Environmental chemistry studies chemical processes occurring in the environment. It focuses on air pollution, water pollution, soil contamination, acid rain, greenhouse effect, ozone depletion, and climate change. This branch plays a crucial role in environmental protection and sustainable development.Royal Society of Chemistry (RSC).

Industrial Chemistry

Industrial chemistry explains large-scale chemical manufacturing processes used in industries. Major topics include petrochemicals, fertilizers, cement, paper, polymers, dyes, detergents, and pharmaceuticals. It bridges laboratory chemistry and commercial production.NCERT

Biochemistry

Biochemistry is the branch of chemistry that studies the chemical processes within living organisms. It includes carbohydrates, proteins, enzymes, lipids, vitamins, hormones, and nucleic acids. Biochemistry is fundamental to medicine, genetics, biotechnology, and molecular biology.

Analytical Chemistry

Analytical chemistry focuses on the qualitative and quantitative analysis of substances. It uses classical chemical methods and modern instrumental techniques such as chromatography, spectroscopy, and electrochemical analysis to determine composition and purity.
