Chemistry - Practical Chemistry

Practise 18 JEE Advanced previous year questions on Practical Chemistry, compiled from papers spanning 2006 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JEE Advanced tests.

Practical Chemistry has been asked in 13 of the 27 years of JEE Advanced papers analysed (2000–2026), with 18 questions in all. 39% of them were easy, 50% moderate and 11% tough. Most of its questions came from 2012, with 3 questions that year. In the last three years (2024–2026) it had 2 questions across 6 papers, about 0.3 per paper.

The chapter's 4 topics are not weighted equally: Identification of Basic Radicals (11 questions, 61%), Preliminary Tests (4 questions, 22%), and Radicals (2 questions, 11%) have been asked the most. Identification of Basic Radicals has also led over the last five years, with 1 question. Identification of Basic Radicals has produced the most tough questions (1).
