Green chemistry emphasizes on

Options

A. Reaction that takes place in non-aqueous medium
B. Utilization of sciences to reduce adverse impact on environment
C. Use of condensation polymers
D. Minimise the use of non-hazardous waste

Answer

**Step-by-Step Solution:**

1. **Understanding Green Chemistry**: Green chemistry is defined as an area of chemistry and chemical engineering focused on designing products and processes that minimize or eliminate the generation of hazardous substances.

2. **Identifying Key Principles**: The main principles of green chemistry include reducing the consumption of non-renewable resources, preventing pollution, and minimizing the use of hazardous substances.

3. **Analyzing the Options**:
- **Option 1**: "Reaction that takes place in non-aqueous medium" - This is not a primary focus of green chemistry.
- **Option 2**: "Utilization of science to reduce adverse impact on the environment" - This aligns with the core principles of green chemistry.
- **Option 3**: "Use of condensation polymers" - This is not a focus of green chemistry.
- **Option 4**: "Minimize the use of non-hazardous waste" - This is incorrect as green chemistry aims to minimize hazardous waste, not non-hazardous waste.

4. **Conclusion**: Based on the analysis, the correct answer is **Option 2**: "Utilization of science to reduce adverse impact on the environment."
