Question

Define: Green chemistry. Write two advantages of nanoparticle and nanotechnology.

Hint:

Green chemistry emphasizes eco-friendly processes; nanoparticles excel due to size-dependent properties.

Answer 1

Definition: Green chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances, promoting sustainability and environmental safety.
Advantages of Nanoparticles and Nanotechnology:
1. **Enhanced Reactivity:** Nanoparticles have a high surface area-to-volume ratio, increasing efficiency in catalysis and drug delivery.
2. **Targeted Applications:** Nanotechnology enables precise targeting (e.g., in medicine for cancer treatment), reducing side effects and improving efficacy.
