Functional Group Priority

JEE Main asked Functional Group Priority 7 times in 7 of the 108 shifts Lumi analysed, in 2020, 2022, 2023, 2024, 2025 and 2026. It belongs to IUPAC Nomenclature, in Organic Chemistry: Some Basic Principles and Techniques (Chemistry). The longest wait between two years asking it was 2 years. In 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, 2024, 2025 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
