Chemistry - Hydrocarbons

Practise 170 MHTCET previous year questions on Hydrocarbons, 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 MHTCET tests.

Hydrocarbons has been asked in 15 of the 17 years of MHTCET papers analysed (2007–2026), with 170 questions in all. 46% of them were easy, 47% moderate and 6% tough. Most of its questions came from 2026, with 28 questions that year. In the last three years (2024–2026) it had 76 questions across 59 papers, about 1.3 per paper.

The chapter's 10 topics are not weighted equally: Properties and Preparation of Alkanes (47 questions, 28%), Reactions of alkenes (38 questions, 22%), and Reactions of alkanes (22 questions, 13%) have been asked the most. Over the last five years the most frequent topics have been Reactions of alkenes (33), Properties and Preparation of Alkanes (28), and Reactions of aromatic compounds (13).
