Concept: Green chemistry is a modern philosophical approach to chemical research and engineering that encourages the design of products and processes that minimize the use and generation of hazardous substances.
• Goal: To make chemistry more environmentally friendly by preventing pollution at the source.
• Principles: It involves 12 principles, such as "Atom Economy," using "Safe Solvents," and "Designing Safer Chemicals."
Step 1: Correct common misconceptions.
Green chemistry is NOT just the study of plants (botany) or natural products. It is about the process of chemistry itself. It focuses on using scientific knowledge to reduce environmental impact while still allowing for technological development.
Step 2: Identify the correct definition.
Option (D) accurately describes Green Chemistry as the application of chemical knowledge to reduce hazards throughout the lifecycle of a chemical product, from design to disposal.
