Hydrolysis of sucrose with dilute aqueous sulphuric acid yields

Step-by-step solution

On hydrolysis with dilute aqueous sulphuric acid, sucrose gives a equimolar mixture of D-(+) glucose and D-(-)-fructose. C ₁₂ H ₂₂ O ₁₁+ H ₂ O H ₂ SO ₄ sucrose C ₆ H ₁₂ O ₆+ C ₆ H ₁₂ O ₆ D-(+) glucose D-(-) fructose 1 : 1 arter hydrolysis Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory and laevorotatory fructose, laevorotatory fructose is more, so the mixture is laevorotatory.
