Q. The correct observation in the following reactions is :
Sucrose $\xrightarrow[\text{Cleavage (Hydrolysis)}]{\text{Glycosidic bond} } A+B \xrightarrow[\text{reagent }]{\text{Seliwanoff 's} } $

JEE MainJEE Main 2020Biomolecules

Solution:

Seliwanoff's test is used to distinguish between aldose and ketose sugars; when added to a solution containing ketose, red colour is formed rapidly.

Sucrose $\xrightarrow{\text{Hydrolysis}} \underset{\overset{+}{\text{Fructose}}}{\text{Glucose}} \xrightarrow[\text{reagent}]{\text{Seliwanoff's}}$ Red colour
