Here is a list of the twenty most sought out for branches of chemistry:

• General chemistry
• General chemistry introduces the essential ideas that explain how matter is structured and how it behaves. It covers atomic theory the periodic table bonding patterns energy changes and the interactions that lead to chemical reactions. Students learn why substances have different colours melting points densities and electrical properties. This branch builds the framework that supports every other area of chemistry because it explains the basic rules that all elements and compounds follow. Without general chemistry it would be difficult to understand the deeper levels of molecular science that appear in higher course

• Organic chemistry
• Organic chemistry focuses on carbon containing compounds and the enormous number of structures that carbon atoms can form. Carbon can create long chains branched networks and complex ring systems which allow for millions of possible molecules. This branch explains the reactions that build and transform these molecules which are found in fuels plastics synthetic materials and all living organisms. Organic chemistry is essential in pharmaceutical design and biotechnology because it teaches how molecular structure controls behaviour and function.
