Chemistry: Definition and Branches

Chemistry is a physical science that deals with the study of interactions between matter and energy. It develops the understanding of matter's properties, characteristics, physical and chemical variations. We regard matter as something that has weight and inhabits space. Chemistry deals with the study of atoms which are composed of subatomic particles of protons, neutrons and electrons. The nature of atoms combined, makes up a matter.

Chemistry comprises of many branches that deals with nature of any matter. Here, we will elaborate the main branches of Chemistry. These include Physical, Analytical, Biochemistry, Organic and Inorganic.

Analytical Chemistry:

It is the study of analyzing the chemical elements of samples. Qualitative and Quantitative analysis are main branches of Analytical Chemistry. Qualitative deals with methods and measurements for the determination of substance elements. Quantitative analysis provide knowledge of the identification of an unknown sample.


Study of living organisms is classified as Biochemistry. The research helps in the development of biological phenomenon in the chemical discipline. Study of cancer cells or any other infectious diseases is related to this branch of Chemistry. Biochemistry is also classified in Enzymology, Endocrinology, Clinical Biochemistry, Molecular Biochemistry, Pharmacological Biochemistry and others.

Physical Chemistry:

The study of physical properties and structure of molecules comes under Physical Chemistry. It deals with the combination of physics and chemistry which include principles and methodologies. The impact of chemical structure on a physical property is studied in this branch. Sub-branches include Electrochemistry, Photochemistry, and Surface chemistry, Chemical Kinetics, Thermochemistry, Quantum Mechanics and Spectroscopy.

Inorganic Chemistry:

The study of elements and compounds that does not own carbon hydrogen bond is Inorganic Chemistry. Non-living things in particular, are the focus of study in this branch. Examples include metals, minerals, catalysts and crystal structures. The sub-division of this group include bioinorganic, Coordination, Geochemistry, Inorganic technology, nuclear chemistry, and organometallic, Synthetic inorganic and Industrial inorganic chemistry.

Organic Chemistry:

It is the Study of chemical compounds in living organisms. Experiments are conducted for the isolation and synthesis of organic compounds. It helps in formulating the components including ketones, aldehydes, hydrocarbons and alcohol. Sub-divisions include Stereochemistry, Medicinal chemistry Organometallic, Physical organic and Polymer chemistry.

Chemistry existed since the oldest civilization, originating from alchemists. Experiments were performed by these alchemists in a methodical order that helped modern science. From 17th century, the era of modern chemistry initiated by one of the prominent founders "Robert Boyle". Regarded as the developer of scientific method, Boyle was the firm believer of logic before acknowledging any scientific theory.
