well ..best explanation is given by ncert as:
Sucrose is dextrorotatory but after hydrolysis it gives dextrorotatory glucose and laevo rotatory fructose ..
since laevo rotation of fructose is -90.4 degree which is more than glucose dextro rotation is whch is + 5 2.5 degree and overall mixture results into laevo rotatory…
thus hydrolysis of sucrose brings about a change in the sign of rotation from dextro(+) to laevo(-) and product is known as invert sugar.
that’s why hydrolysis of sucrose is also known as inversion of cane sugar.
