JEE Advanced 2026
Paper 2 · Question 4
Chemistry
Carbohydrates - structure and glycosidic linkages
Moderate
Convert the given D-galactose Fischer projection to Haworth one carbon at a time, then set the three stereochemical decisions that turn a galactose plus a fructose into sucralose, and watch three of the four printed options fail.
