Chemistry - Hydrocarbons
Practise 31 VITEEE previous year questions on Hydrocarbons, compiled from papers spanning 2007 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.
Hydrocarbons has been asked in 16 of the 18 years of VITEEE papers analysed (2006–2024), with 31 questions in all. 58% of them were easy, 35% moderate and 6% tough. Most of its questions came from 2013, with 5 questions that year. In the last three years (2022–2024) it had 6 questions across 3 papers, about 2 per paper.
The chapter's 9 topics are not weighted equally: Reactions of aromatic compounds (9 questions, 29%), Reactions of alkenes (5 questions, 16%), and Reactions of alkynes (5 questions, 16%) have been asked the most. Over the last five years the most frequent topics have been Properties and Preparation of Alkanes (2), Preparation and Properties of Benzene (1), and Properties and Preparation of Alkenes (1). Preparation and Properties of Benzene has produced the most tough questions (1).
