Key findings

  1. 01

    Asked in 7 of 8 years with analysed shifts and in 53 of 108 shifts: 75 questions, #24 of 196 topics.

  2. 02

    41% of its questions since 2020 tested an idea no earlier year had asked; 26 repeated an idea from the year before.

  3. 03

    The most repeated idea is Ortho-Para vs Meta Directing, asked 11 times in 11 shifts (2021, 2022, 2024, 2025, 2026), most often as “identify site of electrophilic attack in diagram”.

  4. 04

    JEE Main has asked 21 of the 51 ideas in this topic; 21 have never been asked, directly or inside another question.

  5. 05

    Mostly asked as diagram based (45%); 19% need a numerical answer, 23% are easy and 11% hard. It went up from 0.4 to 0.8 questions a shift since 2024.

  6. 06

    The skill tested most is conceptual (28%), then application (27%).

Questions a shift, year by year

Out of the 25 Chemistry questions in a shift. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift.

New idea, or one asked before?

Each column is a year. Blue questions tested an idea no earlier year had asked; navy ones went back to an idea from an earlier year. 2017 is the first year, so everything in it counts as new. Heights are question counts, and Lumi analysed 1 to 24 shifts a year, so compare the split inside a column rather than heights across years.

Squares are the 8 years with analysed shifts, 2017 to 2026. A number is the questions that year when there is more than one; the shade is scaled to one shift, so a year with more analysed shifts (1 to 24 a year) does not look darker. Share is of the level above.
