Analysis of JEE Main Chemistry Paper
- Compared to the other two sections, JEE Main aspirants found the Chemistry section to be the easiest because there were no challenging questions.
- Some of them, though, were challenging inquiries.
- There was a strong emphasis on Class 12th syllabus, with the majority of questions in the JEE Main Chemistry section coming from NCERT textbooks.
- Candidates taking the exam in January 2023 are therefore advised to concentrate on Class 12th and Class 11th topics as well.
Scope of Chemistry
One of the key subjects in the JEE Main entrance exam is chemistry. Inorganic Chemistry, Organic Chemistry, and Physical Chemistry are the three divisions of Chemistry. Typically, theoretical questions from this subject are asked in exams. It is a field of science that focuses on understanding the composition, structure, and characteristics of matter. Additionally, it deals with the investigation of how various types of matter behave differently under various circumstances.
Your daily life is full of instances where chemistry, its use, and its principles are involved. Several of them are listed below:
- Scope of Chemistry in Food Production: Chemical fertilisers like calcium superphosphate, ammonium sulphate, sodium nitrate, and urea have been made possible by chemical research in chemistry. The use of some efficient insecticides has helped farmers protect their crops from pests and harmful bacteria. Preservatives were discovered thanks to chemistry.
- Scope of Chemistry in Industry: Chemistry is important and useful in the growth and development of many industries. Cement, glass, textiles, leather, etc. are a few examples. Nitric acid, sulfuric acid, and ammonia production have all increased as a result.
- Scope of Chemistry in protecting the environment: Science has given us chemicals that are safe for the environment, aiding in environmental conservation. Replace CFCs in the refrigerator, for instance.
- Scope of Chemistry in War: The discovery of highly explosive substances like dynamite, nitroglycerine, and TNT was greatly aided by chemistry. Additionally, it aids in the detection of toxic gases like mustard gas and phosgene.
