Question

Assertion (A) Sucrose is called an invert sugar.
Reason (R) On hydrolysis, sucrose bring the change in the sign of rotation from dextro $(+)$ to laevo $(-)$.$\left(+52.5^{\circ }\right)$ and laevorotation of fructose $\left(-92.4^{\circ }\right)$.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; $R$ is not the correct explanation of $A$.
• C. $A$ is correct but $R$ is incorrect.
• D. $R$ is correct but $A$ is incorrect.

Answer 1

Answer: (A)

The hydrolysis of sucrose brings about a change in the sign of rotation from dextro $(+)$ to laevo $(-)$ and the product is named as invert sugar.
