If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

Vedclass · Answer

(B) Sucrose is a disaccharide with a specific optical rotation of $+66.5^\circ$. Upon hydrolysis,it yields $1 \ mole$ of $D-(+)$ glucose and $1 \ mole$ of $D-(-)$ fructose. The resulting mixture is laevorotatory (net rotation is negative),which is why the process is known as the inversion of cane sugar. While both statements are factually correct,the fact that sucrose is a disaccharide does not explain why its hydrolysis is called inversion; the explanation lies in the change of optical rotation from dextrorotatory to laevorotatory.

Assertion : Hydrolysis of sucrose is known as inversion of cane sugar.
Reason : Sucrose is a disaccharide.
