Chemistry - Solid State

Practise 14 BITSAT previous year questions on Solid State, compiled from papers spanning 2009 to 2023. 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.

Solid State has been asked in 12 of the 16 years of BITSAT papers analysed (2009–2024), with 14 questions in all. 36% of them were easy, 43% moderate and 21% tough. Most of its questions came from 2023, with 2 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 4 topics are not weighted equally: Cubic system (5 questions, 36%), Crystal Structure of Solids (4 questions, 29%), and Stoichiometric defects (4 questions, 29%) have been asked the most. Over the last five years the most frequent topics have been Crystal Structure of Solids (3) and Stoichiometric defects (2). Cubic system has produced the most tough questions (2).
