Intro 🎉

Imagine a world where chemists were superheroes, using their powers not just for cool explosions but to save the environment. Welcome to Green Chemistry! 💥🌍

Traditional vs. Green Chemistry

  • Traditional Chemistry: Focuses mainly on product yield and cost.
  • Green Chemistry: Considers the environment! It looks at toxicity, energy use, and waste.

Real-World Example: It's like comparing buying a cheap, unhealthy burger 🍔 vs. spending a bit more on a healthy, eco-friendly salad 🥗. Sure, the burger is quick and cheap, but the salad has longer-term benefits for you and the planet.

Principles of Green Chemistry (Created in 1991 by Paul Anastas & John Warner)

  • Minimize hazardous chemicals.
  • Use non-toxic solvents.
  • Reduce energy consumption.
  • Use renewable materials.
  • Prioritize safety and prevent accidents.
  • Main mantra: Don't produce waste in the first place!

Did you know? These principles are now part of many international laws!

Atom Economy - A shiny new way to measure efficiency.

  • Formula:atom economy=\(\frac{molar\ mass\ of\ desired\ product}{total\ molar\ of\ reaction\ mixture}\)× 100 %

  • Example: If you have a reaction A + B → C, the atom economy can be almost 100% (that's like getting full marks on a test! 🌟). But if the reaction is A + B → C + D with D as an unwanted by-product, the atom economy drops (like that one tricky question you didn't see on the exam 🤦‍♂️).
