Study Notes
Chemistry is a vast field of science dealing with matter and its interactions, including how things react together and change over time. It's divided into three main branches: Organic, Inorganic, and Physical chemistry. Each branch studies different aspects of chemical reactions and properties of materials. Here we will explore each one briefly.
Organic Chemistry: This focuses on compounds based on carbon. These have chains of atoms linked up like links in a chain. They can be very complicated structures made from thousands of atoms. Many important drugs, such as aspirin, vitamins, and antibiotics, come under this category. Aspirin comes from a substance called salicylic acid, which has been around for millions of years! This kind of chemistry involves lots of reactions between molecules, some of them quite complex. Chemists often make new kinds of molecular structure by getting molecules to bond together.
Inorganic Chemistry: Unlike organic chemistry, this deals with all elements except carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, selenium, silicon, germanium, arsenic, antimony, tellurium, polonium, and astatine. Most metals, minerals, and rocks belong to this section. Metallurgists study it to find out what combinations of material work best when making metal objects like cars and computers.
Physical Chemistry: This branch looks closely at how chemicals behave physically, rather than being concerned just with their composition. For example, chemists talk about energy levels in molecules. If they get a lot more energy, molecules vibrate faster and stronger and may break apart completely. Heating something causes some molecules to move much faster; if you heat ice water, it turns into liquid because the bonds holding one sort of water molecule together become less strong. This type of chemistry includes thermodynamics—how heat flows through systems and changes where energy goes—and kinetics, where speed matters most. Some chemists who do physical chemistry don’t even use reactants: instead they mix solutions and see whether things happen to them!
Chemistry helps us understand many everyday things better. From fertilizers to fuels, paints to pharmaceuticals, this subject plays a vital role across society every day. Whether we realize it or not, chemistry influences our lives profoundly.
