Chemistry - Hydrogen

Practise 32 MHTCET previous year questions on Hydrogen, compiled from papers spanning 2018 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.

Hydrogen has been asked in 8 of the 17 years of MHTCET papers analysed (2007–2026), with 32 questions in all. 75% of them were easy, 19% moderate and 6% tough. Most of its questions came from 2020, with 9 questions that year. In the last three years (2024–2026) it had 14 questions across 59 papers, about 0.2 per paper.

The chapter's 7 topics are not weighted equally: Preparation and Properties of Hydrogen (10 questions, 31%), Preparation and Properties of Water (6 questions, 19%), and Hydrides (5 questions, 16%) have been asked the most. Preparation and Properties of Hydrogen has also led over the last five years, with 7 questions. Preparation and Properties of Hydrogen has produced the most tough questions (1).
