What are the 6 Major Branches of Chemistry?

Chemistry is one of the most important sciences in the world because it has led to so many advancements in our everyday lives. Chemistry is a broad field of science that has many sub-disciplines. In this article, we will learn about chemistry and its 6 major branches and their definitions.

What are the 6 Major Branches of Chemistry?

The following are the 6 major branches of chemistry:

  • Analytical Chemistry
  • Biological/Biochemistry
  • Inorganic Chemistry
  • Organic Chemistry
  • Physical Chemistry
  • Theoretical Chemistry

What is Chemistry?

Chemistry is the study of matter and its interactions with energy. It is the science of matter and its transformations. Chemistry is the most fundamental science. 

Chemistry can also be defined as a branch of physical science that deals with the composition, structure, properties, behavior, and change of matter. 

Chemists study how chemical reactions affect living organisms, the composition of living organisms, the structure and properties of molecules, and how to make new materials. 

They work to find new ways to produce materials, create new medicines, and even make new types of food. Chemistry is an interesting field because it is not only used in the laboratory but also in everyday life. 

There are many different branches of chemistry that are all based on the science of atoms and molecules. Chemistry is a broad field of science that has many sub-disciplines. Its major branches are the following:

Analytical Chemistry

Analytical chemistry is a scientific discipline concerned with the chemical analysis of materials and the chemical processes used in industry. 

Analytical chemists are involved in the design, development, and use of instruments, devices, software, and methods for the chemical analysis of materials. 

They also work to ensure that the analytical chemistry profession is safe, ethical, and effective. Analytical chemistry is the process of analyzing and interpreting the physical properties of materials, molecules, and other particles. 

The most common application of analytical chemistry is in the field of food science, where scientists use analytical chemistry to test food for contaminants, such as bacteria, pesticides, and heavy metals. 

In analytical chemistry, chemists use a variety of tools to obtain, process, and communicate information about the structure of materials. 

These tools include mass spectrometry, X-ray crystallography, nuclear magnetic resonance spectroscopy, and gas chromatography.


Biological/Biochemistry is the study of the chemical reactions and processes that happen in living organisms. Biochemistry deals with the study of macromolecules such as proteins, lipids, nucleic acids, and carbohydrates. 

Biochemistry also studies the mechanisms of metabolic pathways and how they are regulated. It is primarily concerned with how organisms use energy and what happens to these reactions when the organism dies. 

Biological/Biochemistry is also concerned with the molecular basis of living organisms, how different types of cells interact, and how these interactions are affected by the environment.

Inorganic Chemistry

Inorganic chemistry is the study of non-carbon-based chemical compounds. Inorganic compounds are typically metals, metalloids, and nonmetals. 

Inorganic compounds make up the majority of the earth’s crust and form the basis of all life on earth. The study of these inorganic compounds includes their chemical reactions, physical properties, and spectroscopic and magnetic properties.

Inorganic chemistry is also a subfield of chemistry that is concerned with the composition, structure, properties, and behavior of inorganic substances.

Organic Chemistry

Organic chemistry is the study of the chemical compounds that make up living organisms. It is a branch of chemistry that deals with carbon compounds and other reactive compounds that are not found in inorganic compounds. 

Organic chemistry also studies how these compounds interact with each other. Organic chemistry is a very broad field and there are many sub-branches that deal with different aspects of the study.

It is also concerned with the structure, properties, reactions, and synthesis of organic compounds. Organic compounds are those that contain carbon, hydrogen, and oxygen.

Organic chemists study both the large molecules that makeup living organisms and the small molecules that make up inanimate objects. They also study the chemical reactions in which organic compounds are involved.

Physical Chemistry

Physical chemistry is the study of matter and its interactions with energy and other forms of matter. It is a branch of chemistry that deals with the behavior of matter as it relates to its structure, composition, and properties. 

The term physical chemistry was first used in 1867 by Rudolf Clausius. It also covers the molecular and atomic structure of substances, chemical reactions, and their effects on the environment. 

The science of physical chemistry may be applied to a wide range of fields, including biology, medicine, engineering, physics, and materials science. The study of physical chemistry can be divided into three major categories: thermodynamics, kinetics, and electrochemistry.

Theoretical Chemistry

Theoretical Chemistry is a branch of chemistry that deals with the logical and mathematical aspects of chemical reactions. It is a subject of study in universities, colleges, and high schools. 

Theoretical Chemistry is a very interesting and exciting field of study because it allows people to apply their knowledge of chemistry to real-life problems. 

Theoretical chemists use mathematical equations to predict chemical reactions, but they also work on experiments to test these predictions. They use these experiments to see if they can create a reaction that they predicted, or if they need to make changes to their calculations.


Chemistry is the study of matter and its properties, reactions, and transformations. Chemistry is a science that deals with the composition, structure, properties, interactions, and change of matter. Chemistry is essential in many fields such as chemistry, physics, biology, engineering, materials science, etc. This is because chemistry has been used to find new ways to produce energy from fossil fuels and nuclear energy sources.

Frequently Asked Questions (FAQs): What are the 6 Major Branches of Chemistry?

What are the basic components of chemistry? 

Chemistry is the study of matter and its interactions with energy. The basic component of chemistry is the atom and molecules. Atoms are the smallest particles of an element, consisting of protons, neutrons, and electrons. The electron cloud in an atom gives it a negative charge, while the nucleus contains protons and neutrons. Molecules are composed of two or more atoms held together by chemical bonds. Chemistry is the study of matter, how it changes, and how it behaves. It is the science of how atoms and molecules interact to form chemical compounds and how these compounds react with each other.

Who is called the father of chemistry?

Antoine Laurent Lavoisier was a French chemist who contributed to the fields of chemistry, mathematics, and physics. He is often referred to as the “father of modern chemistry” Lavoisier is best known for his work on the law of conservation of mass, which states that in chemical reactions, no matter what reactants are used, the same amount of mass is always released as products.

Who discovered the atom?

John Dalton, a British chemist, discovered the atom in 1803. He was the first to identify that atoms are the smallest particles of an element that can still have chemical properties. John Dalton’s other contributions to chemistry include the law of multiple proportions and the law of definite proportions.
