Which statement best describes the aim of green chemistry?

• A. Green chemistry seeks to minimize waste and avoid hazardous substances.
• B. Green chemistry requires high energy input
• C. Green chemistry only applies to organic synthesis
• D. Green chemistry discourages solvent recycling

Answer: (A)

Green chemistry aims to design chemical processes and products that reduce environmental impact. The main goal is to minimize waste and avoid hazardous substances, so that reactions and products are safer for people and ecosystems while using resources more efficiently. This description best captures the essence of green chemistry, combining waste prevention with hazard reduction—the two central aims of its philosophy. It isn’t about requiring high energy input; in fact, energy efficiency is a key principle, often pursued by running reactions under milder conditions or using safer energy sources. It also applies beyond organic synthesis to all areas of chemistry, including inorganic and materials chemistry. And it encourages solvent recycling and other waste-reducing practices, not discouraging them.
