Current Question (ID: 17894)

Question:

$\text{The correct statement(s) regarding green chemistry is/are:}$

Options:

1. $\text{It helps in decreasing environmental pollution.}$
2. $\text{It prevents or limits chemical pollutants from being introduced into the environment.}$
3. $\text{It reduces the use and generation of substances hazardous to the environment.}$
4. $\text{All of the above.}$

Solution:

$\text{HINT: Green chemistry is focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances.}$ $\text{Explanation:}$ $\text{The release of different harmful chemicals (particulates, gases, organic and inorganic wastes) causes environmental pollution.}$ $\text{In green chemistry, the reactants to be used in chemical reactions are chosen in such a way that the yield of the end products is up to 100\%.}$ $\text{This prevents or limits chemical pollutants from being introduced into the environment.}$ $\text{Through the efforts of green chemists, } \text{H}_2\text{O}_2 \text{ has replaced tetrachloroethane and chlorine gas in drying and bleaching of paper.}$
