Question:
Which of the following is used as Green solvent?
Which of the following is used as Green solvent?
Show Hint
In green chemistry, supercritical \(\text{CO}_2\) is a very important solvent because it is safer and can be removed easily after the reaction.
Updated On: May 14, 2026
- Supercritical \(\text{CO}_2\)
- \(\text{CHCl}_3\)
- \(\text{CH}_2\text{Cl}_2\)
- \(\text{CCl}_4\)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Green solvents are environmentally safer solvents that reduce pollution and are less harmful compared to conventional organic solvents. Supercritical \(\text{CO}_2\) is widely used as a green solvent because it is non-toxic, non-flammable, easily removable, and environmentally safer.
Step 1: Identify the solvent known for green chemistry applications.
Among the given options, supercritical \(\text{CO}_2\) is a commonly used green solvent.
Step 2: Check the remaining options.
\(\text{CHCl}_3\), \(\text{CH}_2\text{Cl}_2\), and \(\text{CCl}_4\) are chlorinated organic solvents and are not considered green solvents because of their toxicity and environmental hazards. Hence, the correct answer is:
\[ \boxed{(A)\ \text{Supercritical } \text{CO}_2} \]
