Chemistry - Solid State

Practise 56 NEET previous year questions on Solid State, compiled from papers spanning 2002 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 NEET tests.

Solid State has been asked in 22 of the 39 years of NEET papers analysed (1988–2026), with 56 questions in all. 43% of them were easy, 46% moderate and 11% tough. Most of its questions came from 2008, with 9 questions that year. In the last three years (2024–2026) it had 0 questions across 13 papers, about 0 per paper.

The chapter's 7 topics are not weighted equally: Cubic system (43 questions, 77%), Stoichiometric defects (5 questions, 9%), and Non-stoichiometric defects (3 questions, 5%) have been asked the most. Cubic system has also led over the last five years, with 5 questions. Cubic system has produced the most tough questions (4).
