  2. Renewable feedstocks

  3. Energy efficiency

  4. Increased toxicity


Correct Option: D
Explanation:

Green chemistry principles focus on reducing toxicity and environmental impact, not increasing it.

What is the concept of atom economy in green chemistry?

  1. Maximizing the utilization of atoms in a chemical reaction

  2. Minimizing the number of steps in a chemical process

  3. Using renewable energy sources in chemical processes

  4. Reducing the amount of waste generated in a chemical reaction


Correct Option: A
Explanation:

Atom economy emphasizes the efficient use of atoms in a chemical reaction, minimizing waste and maximizing the incorporation of atoms into the desired product.

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

  1. Petroleum

  2. Natural gas

  3. Coal

  4. Biomass


Correct Option: D
Explanation:

Biomass, such as plant-based materials and agricultural waste, is a renewable feedstock because it can be replenished naturally.

What is the significance of energy efficiency in green chemistry?

  1. Reducing the amount of energy required for a chemical process

  2. Increasing the rate of a chemical reaction

  3. Maximizing the yield of a chemical product

  4. Improving the quality of a chemical product


Correct Option: A
Explanation:

Energy efficiency in green chemistry aims to minimize the energy consumption of chemical processes, reducing greenhouse gas emissions and conserving resources.

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

  1. Dichloromethane

  2. Methanol

  3. Benzene

  4. Carbon tetrachloride


Correct Option: B
Explanation:

Methanol is a green solvent due to its low toxicity, biodegradability, and renewability compared to traditional organic solvents.

What is the concept of life cycle assessment (LCA) in sustainability?

  1. Evaluating the environmental impact of a product or process throughout its entire life cycle

  2. Assessing the economic feasibility of a sustainable practice

  3. Measuring the social benefits of a sustainable initiative

  4. Determining the energy efficiency of a manufacturing process


Correct Option: A
Explanation:

LCA is a tool used to comprehensively assess the environmental impacts of a product or process, considering all stages from raw material extraction to end-of-life disposal.

Which of the following is a key aspect of sustainable design?

  1. Using recycled materials in product manufacturing

  2. Designing products for easy disassembly and recycling

  3. Incorporating energy-efficient features into products

  4. All of the above


Correct Option: D
Explanation:

Sustainable design encompasses a range of strategies, including using recycled materials, designing for easy recycling, and incorporating energy-efficient features, to minimize environmental impact.

What is the significance of eco-labeling in promoting sustainability?

  1. Providing consumers with information about the environmental impact of products

  2. Encouraging companies to adopt sustainable practices

  3. Setting standards for sustainable product manufacturing

  4. All of the above


Correct Option: D
Explanation:

Eco-labeling plays a crucial role in sustainability by informing consumers, encouraging companies to adopt sustainable practices, and setting standards for sustainable product manufacturing.

Which of the following is an example of a sustainable energy source?

  1. Fossil fuels

  2. Nuclear energy

  3. Solar energy

  4. Hydropower


Correct Option: C
Explanation:
