Main Branches of Chemistry

The branch of science which we study the composition,structure,properties,and reaction of a matter or substance is called chemistry.
Although many would say that there are FIVE main branches of chemistry, namely: Physical, Analytical, Biochem-istry, Organic and Inorganic chemistry many would argue that the science of chemistry actually links out to other branches or sub-branches that include Materials Chem-istry, Theoretical Chem-istry, macro molecular (Polymer) Chemistry, Nuclear Chem-istry, Metallurgy, Forensic Chemistry, Medicinal Chem-istry and more.

It is important to note that often sub-branches fall under one or more of the main branches of chem-istry..
Let’s start by taking a look at the 5 main branches of chem-istry :

Analytical chemistry:

Analytical chemistry is the study involving how we analyze the chemical components of samples. How much caffeine is really in a cup of coffee? Are there drugs found in athlete’s urine samples? What is the pH level of my swimming pool?
Examples of areas using analytical chemistry include forensic science, environmental science, and drug testing.
Analytical chemistry is divided into two main branches: qualitative and quantitative analysis.
Qualitative analysis employs methods/measurements to help determine the components of substances. Quantitative analysis on the other hand, helps to identify how much of each component is present in a substance.


The study of life or more suitably put, of chemical processes in 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.
Biochemistry, can also be explained as a discipline in which biological phenomena are examined in chemical terms. Examples are digestion and cellular respiration.
For this reason biochem-istry is also known as Chemical Biology or Biological Chem-istry.

Inorganic  Chem-istry:

Chemists in this field focus on elements and compounds other than carbon or hydrocarbons. Simply put, inorganic chem-istry covers all materials that are not organic and are termed as non-living substances – those compounds that do not contain a carbon hydrogen (C-H) bond.
Compounds studied by inorganic chemists include crystal structures, minerals, metals, catalysts, and most elements on the periodic table. An example is the strength of a power beam used to carry a specific weight or investigating how gold is formed in the earth.

Organic Chem-istry:

The study of carbon compounds such as fuels, plastics, food additives, and drugs. An opposite of inorganic chem-istry that focuses on non-living matter and non-carbon based substances, organic chemistry deals with the study of carbon and the chemicals in living organisms. An example is the process of photosynthesis in a leaf because there is a change in the chemical composition of the living plant.

Physical Chem-istry:

The study of the physical properties of molecules, and their relation to the ways in which molecules and atoms are put together. Physical chem-istry deals with the principles and methodologies of both chem-istry and physics and 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.
