Net Dipole Moment from VSEPR Symmetry

JEE Main asked Net Dipole Moment from VSEPR Symmetry 8 times in 7 of the 108 shifts Lumi analysed, in 2020, 2022, 2023 and 2024. It belongs to VSEPR Theory, in Chemical Bonding and Molecular Structure (Chemistry). The longest wait between two years asking it was 2 years. In 2022 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
