Why sucrose is called invert sugar ?...

Why sucrose is called invert sugar ? 

Text Solution

Verified by Experts

Natural sucrose is dextrorotatory with `[alpha]_(D)=+66.5^(@)`. When it is hydrolysed forms D-glucose with `[alpha]_(D)=-92.4^(@)`.
and D-fructose with `[alpha]_(D)=-92.4^(@)`.
Then the resultant mixture becomes leavo rotatory. So it is called invert sugar.
