What comes to your mind when you hear the word Chemistry? Maybe scientists working on a bench dealing with different chemicals, or how different chemicals react together, or even about models of different molecules. But Chemistry is much more to that. It is one of the sciences that help us understand and make models and predictions about our reality. Pure Chemistry is further divided into five main branches. Let us learn about them.


The Main Branches Of Chemistry

There are five main branches namely:

  • Organic Chemistry.
  • Inorganic Chemistry.
  • Bio-Chemistry.
  • Physical Chemistry.
  • Analytical Chemistry.

Organic Chemistry

It is a branch of Chemistry that deals with the compounds that contain Carbon and Hydrogen. It involves the study of structures and preparation of C-H bonds, example: Petroleum, medicines, foods, and process of photosynthesis.

Sub-branches of Organic Chemistry include:

  • Stereochemistry.
  • Organometallic chemistry
  • Physical Organic Chemistry.
  • Medicinal Chemistry.
  • Polymer Chemistry.

Inorganic Chemistry

It is a branch of Chemistry that deals with the compounds that are made up of only one or no Carbon atoms. It deals with all chemical compounds except organic compounds. The chemists who usually study this branch deal with the study of crystal structures, minerals, metals, catalysts, and most elements on the periodic table.

Sub-branches of Organic Chemistry include:

  • Bioinorganic chemistry.
  • Coordination chemistry.
  • Geochemistry.
  • Inorganic technology.
  • Nuclear chemistry.
  • Organometallic chemistry.
  • Solid-state chemistry.
  • Synthetic inorganic chemistry.
  • Industrial inorganic chemistry.

Inorganic Chemistry


It is a branch of Chemistry that deals with the chemicals changes/reactions that occur inside living organisms. Biochemists research includes cancer and stem cell biology, infectious disease as well as membrane and structural biology and spans molecular biology, genetics, mechanistic biochemistry, genomics, evolution, and systems biology.

Sub-branches of Bio-Chemistry include:

  • Enzymology.
  • Endocrinology.
  • Clinical Biochemistry.
  • Molecular Biochemistry.

Physical Chemistry

It is a branch of Chemistry that deals with the study of physical properties of molecules. It deals with the principles and methodologies of both chemistry and physics. Basically, it is the study of how chemical structure impacts physical properties of a substance. An example is baking brownies, as you’re mixing materials and using heat and energy to get the final product.

Sub-branches of Physical Chemistry include:

  • Electrochemistry.
  • Photochemistry.
  • Surface chemistry.
  • Chemical Kinetics.
  • Thermodynamics.
  • Quantum Mechanics.
  • Spectroscopy.

Analytical Chemistry

It is the branch of Chemistry that deals with the study of separation and identification of the chemical components of natural and artificial compounds. The qualitative analysis employs measurements to help determine the components of substances and it is more on the physical properties and identity. Quantitative analysis, on the other hand, helps to identify how much of each component is present in a substance.

Sub-branches of Analytical Chemistry include:

  • Forensic Chemistry.
  • Environmental Chemistry.
  • Bioanalytical Chemistry.
