Detailed explanation-1: -3.2 Corrosion inhibitors: the new role of green chemistry. Corrosion inhibitors are chemical substances that, when added in small amounts to the environment in which a metal would corrode, will reduce, slow down or prevent corrosion of the metal.

Detailed explanation-2: -Physical Chemistry This branch of chemistry encompasses the study of the effect of chemical structure on the physical properties of a substance, the rate of chemical reactions, the calculation of properties and structures, and the interaction of molecules with radiation.

Detailed explanation-3: -OrganicOrganic chemistry is a sub-field of chemistry that involves studying the molecules of life. It is mainly concerned with looking at the structure and behavior of these molecules, which are composed of only a few different types of atoms: carbon, hydrogen, oxygen, nitrogen, and a few miscellaneous others.

Detailed explanation-4: -Physical chemistry is the study of macroscopic properties, atomic properties, and phenomena in chemical systems. As examples, a physical chemist may study the rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level.
