Chemistry - Coordination Compounds

Practise 68 TS EAMCET previous year questions on Coordination Compounds, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Coordination Compounds has been asked in 16 of the 24 years of TS EAMCET papers analysed (2001–2024), with 68 questions in all. 38% of them were easy, 44% moderate and 18% tough. Most of its questions came from 2020, with 10 questions that year. In the last three years (2022–2024) it had 16 questions across 17 papers, about 0.9 per paper.

The chapter's 6 topics are not weighted equally: Terminology of coordination compounds (28 questions, 41%), Crystal Field Theory (18 questions, 26%), and Werner's theory and Valence Bond Theory (12 questions, 18%) have been asked the most. Terminology of coordination compounds has also led over the last five years, with 11 questions. Terminology of coordination compounds has produced the most tough questions (4).
