Chemistry - Redox Reactions
Practise 3 NEST (NISER) previous year questions on Redox Reactions, compiled from papers spanning 2022 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 NEST (NISER) tests.
Redox Reactions has been asked in 3 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 3 questions in all. 33% of them were easy, 67% moderate and 0% tough. Most of its questions came from 2026, with 1 question that year. In the last three years (2024–2026) it had 2 questions across 4 papers, about 0.5 per paper.
The chapter's 3 topics are not weighted equally: Oxidation and Reduction Reactions (1 question, 33%), Balancing of redox reactions (1 question, 33%), and Types of redox reactions (1 question, 33%) have been asked the most. Oxidation and Reduction Reactions has also led over the last five years, with 1 question.
