Fun & Interactive Chemistry Quiz

Basic Chemistry Quiz exercises often remind us how much we owe to small accidents in science. Take nylon, for instance. In the 1930s, Wallace Carothers, a chemist at DuPont, wasn’t trying to create a world-changing fabric; he was simply experimenting with long chains of molecules called polymers. One day, he pulled a heated mixture from a beaker and noticed it formed fibres. That “accident” became nylon; flexible, durable, and perfect for replacing silk, which was expensive and hard to source. From toothbrush bristles to parachutes in World War II, nylon quietly revolutionized everyday life. It wasn’t magic, it was chemistry, curiosity, and a bit of luck. If you’re exploring chemistry for beginners or just want a relaxed science quiz, this basic chemistry MCQ set is a great place to start.
