Octahedral Field Splitting

JEE Main asked Octahedral Field Splitting 4 times in 4 of the 108 shifts Lumi analysed, in 2022, 2023 and 2026. It belongs to Crystal Field Theory, in Coordination Compounds (Chemistry). The longest wait between two years asking it was 3 years. In 2022 it came in more than one shift of the same year.
