Friedel-Crafts Alkylation

JEE Main asked Friedel-Crafts Alkylation 7 times in 7 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023 and 2026. It belongs to Aromatic Hydrocarbons, in Haloalkanes and Haloarenes (Chemistry). The longest wait between two years asking it was 3 years. In 2020 and 2026 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021, 2022, 2023 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
