Practise 79 KCET previous year questions on General Organic Chemistry, compiled from papers spanning 2007 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 KCET tests.

General Organic Chemistry has been asked in 20 of the 20 years of KCET papers analysed (2007–2026), with 79 questions in all. 62% of them were easy, 33% moderate and 5% tough. Most of its questions came from 2026, with 8 questions that year. In the last three years (2024–2026) it had 16 questions across 3 papers, about 5.3 per paper.

The chapter's 11 topics are not weighted equally: Isomerism of Organic Compounds (25 questions, 32%), IUPAC Nomenclature (18 questions, 23%), and Electron displacement effects (12 questions, 15%) have been asked the most. Over the last five years the most frequent topics have been IUPAC Nomenclature (6), Isomerism of Organic Compounds (6), and Conjugation and Aromaticity (3). Isomerism of Organic Compounds has produced the most tough questions (1).
