EVERYDAY SCIENCE

Detailed explanation-1: -The last main branch of chemistry is organic chemistry, which studies the properties, behavior, and reactions of organic compounds, which are carbon-based compounds. So, of the options (A) to (E), the only one that is not a recognized branch of chemistry is particle chemistry.

Detailed explanation-2: -The study of modern chemistry can be split into two types of research: pure and applied. Pure research focuses on understanding basic properties and processes. Applied research is directed toward a specific practical goal or application.

Detailed explanation-3: -The field of applied chemistry focuses on applying the theories and principles of chemistry to practical problems, finding out the chemical properties of materials, and developing new materials.

Detailed explanation-4: -Pure chemistry focuses on expanding our understanding of the natural world. Applied chemistry focuses on applying that knowledge to accomplish specific goals.
