What Is the Atom Economy?

The video tutorial explains atom economy, a measure of the efficiency of a chemical reaction in terms of useful product yield. It highlights the importance of high atom economy in reducing waste and promoting sustainable industrial processes. The tutorial provides a step-by-step guide on calculating atom economy using molecular masses, with examples involving dibromoethane and hydrazine reactions. The video emphasizes the need for efficient processes to conserve resources and minimize waste.

What does a high atom economy indicate about a chemical reaction?

• It produces a large amount of waste.

• It is very slow.

• It is highly efficient with minimal waste.

• It uses a lot of energy.

In the example of making dibromoethane, what was the atom economy?

• 50%

• 75%

• 100%

• 25%

Why is the atom economy of the dibromoethane reaction 100%?

• Because it is a reversible reaction.

• Because it uses renewable resources.

• Because it forms only one product with no waste.

• Because it uses a catalyst.

What is the atom economy of the hydrazine production reaction?

• 100%

• 75%

• 50%

• 29.5%

Why is it important for industries to aim for high atom economy in their processes?

• To conserve natural resources and reduce waste.

• To increase the speed of reactions.

• To produce more complex products.

• To reduce costs and increase profits.
