Octahedral and Square Planar

JEE Main asked Octahedral and Square Planar 4 times in 4 of the 108 shifts Lumi analysed, in 2020, 2023 and 2026. It belongs to VSEPR Theory, in Chemical Bonding and Molecular Structure (Chemistry). The longest wait between two years asking it was 3 years. 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 2020, 2023 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
