Free Green Chemistry MCQs with Answers
6 Green Chemistry MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Green chemistry designs chemical processes that reduce waste, hazards, energy use and pollution at the source rather than treating them afterward. Its principles include prevention, atom economy, safer solvents and products, catalysis, renewable feedstocks, energy efficiency, reduced derivatisation and designing substances for degradation.

Correct answer: The acidulation of phosphate rock- A. Burning of waste material in pits
- B. Converting the solid waste into useful products by thermal treatment
- C. Energy recovery from organic matter prior to its final disposal
- D. Size reduction and compaction by thermal process
Explanation: The primary function of thermal treatment is to convert the waste to a stable and usable end product. Therefore the answer will be B.
Correct answer: Converting the solid waste into useful products by thermal treatment- A. Ammonium nitrate
- B. Triple phosphate
- C. Urea
- D. Nitro phosphate
Explanation: The correct answer is Triple phosphate. It is a phosphate fertilizer, primarily providing phosphorus rather than nitrogen.
Correct answer: Triple phosphate- A. 10-30%
- B. 50-90%
- C. 50-75%
- D. 60-75%
Explanation: Biogas is predominantly composed of methane (CH4) and carbon dioxide (CO2).
Correct answer: 50-75%- A. To prevent waste creation
- B. To maximize the atom economy
- C. To create less hazardous synthetic chemical
- D. All of the above
Explanation: The basic principles of green chemistry encompass all the options listed: A.
