Question

Which of the following is NOT a characteristic of a 'green' or sustainable solvent?

A.RAMA NAGESWARARAO · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Green chemistry principles and sustainable solvents
 **Related Topics**: Environmental impact of solvents, solvent properties, biodegradability, renewable resources
 **Prerequisites**: Basic understanding of chemistry and environmental science.
## SOLUTION PATHWAY
**Given Information**:
The question asks to identify the characteristic that is NOT associated with green or sustainable solvents.
**Method & Steps**:
1. Analyze each option to determine if it aligns with the principles of green chemistry.
2. Identify the option that contradicts the principles of green solvents.
 Reasoning: Green solvents aim to minimize environmental impact.  Low toxicity, biodegradability, and derivation from renewable resources all contribute to this goal.
 Formula/Rule:  There is no specific formula, but the understanding of green chemistry principles is key.
3. High flammability is a hazard and increases the risk of fire and other safety issues, directly contradicting the goal of environmental sustainability.
 Result: High flammability is not a characteristic of a green solvent.
 Verification:  The other options are all desirable attributes of green solvents.
 ## OPTION ANALYSIS
A ✓: Low toxicity is a key feature of green solvents, minimizing harm to humans and the environment.
B :x: Biodegradability ensures the solvent breaks down naturally, reducing environmental persistence.
C :x:  Derivation from renewable resources reduces reliance on fossil fuels and promotes sustainability.
D :x: High flammability is a safety hazard and is detrimental to environmental sustainability. This is the correct answer.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing desirable properties with undesirable properties of green solvents:  Carefully consider the meaning of 'green' or sustainable in the context of solvents.
  2.Focusing only on one aspect:  Green solvents require a holistic consideration of toxicity, biodegradability, renewability, and safety.
 **Quick Tips**:
  1.Remember the core principles of green chemistry:  reducing hazards, using renewable resources, and minimizing waste.
  2.Associate 'green' solvents with safety and environmental friendliness.
