The three main branches of chemistry are:

1. Inorganic Chemistry :  This branch studies inorganic compounds such as minerals, coordination compounds, metals, and salts.
2. Organic Chemistry : This branch covers the organic compounds specifically, those that contain carbon-hydrogen bonds. It is essential for understanding the properties, structure, and reactions of many organic substances.
3. Physical Chemistry :  This branch combines principles of chemistry and physics, which helps to understand how chemical reactions occur. Some key concepts, such as kinetics, thermodynamics, and quantum mechanics, are the core of physical chemistry.
