Ambidentate Ligands in Linkage Isomerism

JEE Main asked Ambidentate Ligands in Linkage Isomerism 4 times in 4 of the 108 shifts Lumi analysed, in 2022, 2023 and 2024. It belongs to Coordination Isomerism, in Coordination Compounds (Chemistry). The longest wait between two years asking it was 1 year. In 2023 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.

How JEE Main framed it

Numerical value is the usual form. Skill tested: recall.

  • Odd-one-out among ligand sets
  • Count ligands of a type in complex
