Why sucrose is called invert sugar?
when sucrose is hydrolysed it turns into glucose and fructose.
fructose is laevo rotatory
whereas glucose is dextrorotatory
sucrose is also dextrorotatory
but amout of laevo rotation of fructose is able to overcome the dextro rotation of glucose.
hence the product is laevo rotatory an d reactant dextrorotatory
hence sucrose is an invert sugar.
