Chemistry - Hydrocarbons

Practise 21 BITSAT previous year questions on Hydrocarbons, compiled from papers spanning 2010 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 BITSAT tests.

Hydrocarbons has been asked in 12 of the 16 years of BITSAT papers analysed (2009–2024), with 21 questions in all. 33% of them were easy, 38% moderate and 29% tough. Most of its questions came from 2016, with 4 questions that year. In the last three years (2022–2024) it had 3 questions across 2 papers, about 1.5 per paper.

The chapter's 9 topics are not weighted equally: Reactions of aromatic compounds (7 questions, 33%), Properties and Preparation of Alkenes (3 questions, 14%), and Reactions of alkenes (3 questions, 14%) have been asked the most. Reactions of aromatic compounds has also led over the last five years, with 3 questions. Reactions of aromatic compounds has produced the most tough questions (2).
