Geometry vs Shape Distinction

JEE Main asked Geometry vs Shape Distinction 5 times in 4 of the 108 shifts Lumi analysed, in 2022 and 2023. It belongs to VSEPR Theory, in Chemical Bonding and Molecular Structure (Chemistry). The longest wait between two years asking it was 1 year. In 2022 and 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 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
