Reaction of Esters with Grignard Reagents

JEE Main asked Reaction of Esters with Grignard Reagents 4 times in 4 of the 108 shifts Lumi analysed, in 2017, 2021 and 2024. It belongs to Carboxylic Acids and Derivatives, in Aldehydes, Ketones and Carboxylic Acids (Chemistry). The longest wait between two years asking it was 4 years, across 2018 and 2019, which Lumi has no shifts for. In 2021 it came in more than one shift of the same year.
