Question

Why sucrose is called invert sugar?

Answer 1

Hey there!!


Sucrose is called invert sugar because it inverts the rotation of light
after Hydrolysis.

For ex. If it rotates the light toward left before hydrolysis then it will rotate it toward right after hydrolysis.
(from dextro to levo rotatory)

# hope it helped u!!

Answer 2

Sucrose is dextrorotatory(turns PPL towards right), but on hydrolysis the resulting mixture is of glucose and fructose which is slightly levorotatory ( turns PPL towards left)because the levorotatory fructose has a greater molar rotation than the dextrorotatory glucose. As the rotation of light changes on hydrolysis, it is called as invert sugar.
