Explanation:

Green Chemistry aims to design and develop chemical processes and products that minimize the use and generation of hazardous substances, reduce energy consumption, and prevent pollution.

Which of the following principles is NOT a core tenet of Green Chemistry?

  1. Prevention of waste.

  2. Atom economy.

  3. Use of renewable feedstocks.

  4. Increased energy consumption.


Correct Option: D
Explanation:

Green Chemistry emphasizes the prevention of waste, atom economy, and the use of renewable feedstocks. Increased energy consumption is not a principle of Green Chemistry.

What is the term used to describe chemical reactions that produce minimal or no waste?

  1. Atom-efficient reactions.

  2. Catalytic reactions.

  3. Green reactions.

  4. Sustainable reactions.


Correct Option: A
Explanation:

Atom-efficient reactions are chemical reactions that maximize the incorporation of atoms from the reactants into the final product, resulting in minimal or no waste.

Which of the following is an example of a renewable feedstock?

  1. Fossil fuels.

  2. Biomass.

  3. Minerals.

  4. Metals.


Correct Option: B
Explanation:

Biomass, derived from plant and animal materials, is a renewable feedstock that can be used to produce fuels, chemicals, and materials.

What is the primary advantage of using catalytic reactions in Green Chemistry?

  1. They reduce the need for harsh reaction conditions.

  2. They increase the yield of the desired product.

  3. They minimize the formation of byproducts.

  4. All of the above.


Correct Option: D
Explanation:

Catalytic reactions in Green Chemistry offer several advantages, including reduced reaction conditions, increased product yield, and minimized byproduct formation.

Which of the following is an example of a green solvent?

  1. Water.

  2. Dichloromethane.

  3. Benzene.

  4. Carbon tetrachloride.


Correct Option: A
Explanation:
