30 Green Chemistry Quiz Questions and Answers

Green chemistry, also known as sustainable chemistry or environmentally benign chemistry, is a field of chemistry that focuses on designing chemical processes and products that minimize the generation of hazardous substances and reduce the overall impact on the environment and human health. The primary goal of green chemistry is to develop innovative and sustainable solutions that promote the efficient use of resources, reduce waste, and decrease the use of hazardous chemicals throughout a product’s life cycle.

Key Principles of Green Chemistry:

Prevention: Green chemistry emphasizes preventing pollution at its source rather than treating or disposing of waste. This principle encourages the design of processes that produce fewer hazardous by-products and waste materials.

Atom Economy: It promotes the use of efficient chemical reactions that maximize the incorporation of all reactants into the final product, minimizing waste generation.

Safer Chemicals: Green chemistry advocates for the use of less hazardous chemicals whenever possible, reducing the risk to human health and the environment.

Design for Energy Efficiency: Green chemistry encourages the use of energy-efficient processes to reduce the consumption of energy and lower greenhouse gas emissions.

Renewable Feedstocks: It encourages the use of renewable raw materials as feedstocks for chemical processes, reducing the reliance on non-renewable resources.

Reduce, Reuse, Recycle: Green chemistry promotes the application of the three Rs in chemical processes to minimize waste and promote resource efficiency.
