Chemistry - Hydrogen

Practise 14 BITSAT previous year questions on Hydrogen, 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.

Hydrogen has been asked in 8 of the 16 years of BITSAT papers analysed (2009–2024), with 14 questions in all. 57% of them were easy, 21% moderate and 21% tough. Most of its questions came from 2022, with 4 questions that year. In the last three years (2022–2024) it had 9 questions across 4 papers, about 2.3 per paper.

The chapter's 6 topics are not weighted equally: Preparation and Properties of Hydrogen (4 questions, 29%), Chemical properties of hydrogen peroxide (3 questions, 21%), and Hydrides (3 questions, 21%) have been asked the most. Over the last five years the most frequent topics have been Hydrides (3), Preparation and Properties of Hydrogen (3), and Chemical properties of hydrogen peroxide (2). Chemical properties of hydrogen has produced the most tough questions (1).
