Question

Define Green chemistry. Write two advantages of nanoparticles and nanotechnology.

Hint:

Green chemistry aims to make chemical processes more environmentally friendly by focusing on sustainability and reducing hazards.

Answer 1

1. Green Chemistry: Green chemistry is the design of chemical processes and products that reduce or eliminate the use and generation of hazardous substances. The primary focus is on sustainable practices, minimizing waste, reducing energy consumption, and using renewable resources. Key Principles of Green Chemistry: - Waste prevention, not treatment. - Atom economy, where all atoms in the reactants end up in the products. - Use of renewable feedstocks. 2. Advantages of Nanoparticles and Nanotechnology: - Enhanced Chemical Reactivity: Nanoparticles have a high surface area to volume ratio, which increases their reactivity. This makes them useful in catalysis, drug delivery, and environmental cleanup. - Improved Material Properties: Nanotechnology can improve the strength, durability, and conductivity of materials, which is beneficial for electronics, medical devices, and manufacturing.
