The chemistry of the natural environment and pollutant compounds in nature is known as environmental chemistry, whereas green chemistry focuses on reducing and preventing pollution at its source. Green chemistry is described as chemistry that is benign to the environment. Green chemistry is currently one of the most researched topics. Green chemistry study strives to reduce or eliminate the generation of harmful bi-products while maximizing desired products in an environmentally sustainable manner. The utilization of supercritical carbon dioxide, water as a green solvent, aqueous hydrogen peroxide as an oxidizing agent, and hydrogen in asymmetric synthesis are the three main developments in green chemistry. Green Chemistry reduces pollution by employing a number of environmentally friendly methods relative to conventional processes.
