Chemistry is a big part of our daily lives, even if we don’t always notice it. In Class 12 Chemistry, the topic Chemistry in Everyday Life helps us understand how chemical substances and reactions affect what we do every day. This topic shows how important chemistry is by using examples we can all relate to.
We use chemistry in many ways, like when we clean our clothes with detergents, use medicines to feel better, or keep our food fresh with preservatives. This chapter explains different types of drugs, how they work, and how chemicals are used in things like food and cleaning products. The Multiple Choice Questions (MCQs) on Chemistry in Everyday Life help you understand these ideas better. They prepare you for exams and show you how chemistry makes our lives easier and safer.
