During the acidic hydrolysis of sucrose, the specific rotation of the solution changes from dextroro — Biomolecules Chemistry Question

💡 Solution & Explanation

Acid hydrolysis of sucrose ($+66.5^\circ$) yields equimolar D-glucose ($+52.5^\circ$) and D-fructose ($-92.4^\circ$). Because the laevorotation of fructose dominates, the net mixture is laevorotatory and is called invert sugar.
