Carboxylic Acid Acidity

JEE Main asked Carboxylic Acid Acidity 5 times in 5 of the 108 shifts Lumi analysed, in 2020, 2021, 2024 and 2026. It belongs to Organic Acidity and Basicity, in Alcohols, Phenols and Ethers (Chemistry). The longest wait between two years asking it was 3 years. In 2024 it came in more than one shift of the same year.
