This document provides instructions and questions for an internal assessment test in Green Chemistry for a Bachelor of Science in Chemistry (Honours) program. It lists 7 questions related to topics in green chemistry, including examples of atom-economical and uneconomical reactions, calculating atom economy, limitations of using yields and atom economy as efficiency measures, examples of green organic reactions using microwave irradiation, the relationship between green chemistry and sustainable development, green syntheses of specific compounds highlighting green chemistry principles, and assessing whether a given conversion follows green chemistry principles. Students are instructed to answer any 5 of the 7 questions in their own words within the allotted time and provide their name, registration details, and university on the answer paper.
