Question:
Which of the following processes is according to principles of green chemistry?
Which of the following processes is according to principles of green chemistry?
Show Hint
Choose the option that reduces hazard, waste or energy use.
Updated On: Nov 12, 2026
- Running reactions at high temperatures to maximize production
- Burning chemical waste for quick disposal
- Replacing hazardous solvents with water or ethanol in synthesis
- Increasing the use of petroleum-based feedstocks
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Green chemistry aims to reduce hazardous substances, waste and energy use.
Step 2: Evaluate
High temperature raises energy use, burning waste causes pollution and more petroleum feedstock is not renewable.
Step 3: Best Choice
Replacing hazardous solvents with water or ethanol follows the principle of safer solvents.
Final Answer:
Replacing hazardous solvents with water or ethanol follows green chemistry. \[ \boxed{\text{(C) }\text{Replacing hazardous solvents with water or ethanol in synthesis}} \]
