The smog having high contents of SO2 is called:
Correct answer: D. Reducing smog
- A. Oxidising smog
- B. Neutral smog
- C. Basic smog
- D. Reducing smog
Explanation
Smog is a combination of smoke and fog. There are two types of smog: oxidising and reducing.Oxidising smog is also called photochemical smog and it consists of high concentration of oxidants like ozone.Reducing smog contains high contents of SO2; it is chemically reducing by nature. It gets oxidised to SO3 first and then dissolves in water to form H2SO4 to produce acid rain.Therefore, option D is the correct answer.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
