Question

Invert sugar is:

• A. a type of cane sugar
• B. optically inactive form of sugar
• C. mixture of glucose and galactose
• D. mixture of glucose and fructose in equimolar quantities

Answer 1

The correct option is D mixture of glucose and fructose in equimolar quantities

Sucrose which is an equimolar mixture of glucose and fructose on hydrolysis brings about a change in the sign of rotation from dextro (+) to laevo (-) and the product is named as invert sugar.

Hence, invert sugar is a mixture of glucose and fructose in equimolar quantities.
