Question

Which of the following is not an objective of Green chemistry?

• A. It is better to prevent waste than to treat or clean up waste after it has been created.
• B. The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.
• C. Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
• D. None of the above

Answer 1

The correct option is D None of the above

All the three are objectives of Green chemistry.
1. Waste Prevention:
It is better to prevent waste than to treat or clean up waste after it has been created.
2. Safer Solvents and Auxiliaries:
The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.
3. Design for Energy Efficiency:
Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.
