Trigonal Bipyramidal Positions

JEE Main asked Trigonal Bipyramidal Positions 5 times in 5 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2024 and 2025. It belongs to VSEPR Theory, in Chemical Bonding and Molecular Structure (Chemistry). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021, 2022, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
