CUET Domain Subject Chemistry Question No: 4
Invert sugar is a mixture of
Option A : D-glucose + D-fructose
Option B : L-glucose + D-fructose
Option C : L-glucose + D-glucose
Option D : L-glucose + L-glucose
Show/Hide Answer Key
Option A: D-glucose + D-fructose
Invert sugar is a mixture of D-glucose and D-fructose. Sucrose is also known as invert sugar. Solution of sucrose is dextrorotatory. When sucrose is hydrolysed it forms equimolar quantity of D-glucose and D-fructose. The solution of formed products is found to be laevorotatory. This change in optical properties of sucrose is called inversion of cane sugar. The equimolar product is formed, i.e. D-glucose and D-fructose is called invert sugar.
