Q. Fructose reduces tollens reagent due to______

AP EAMCETAP EAMCET 2020

Solution:

Tollen's reagent is $\left( AgNO _{3}+ NH _{4} OH \right)$ and it enables basic medium. Fructose is a keto-hexose, still it can reduce Tollen's reagent. Because in basic medium, it undergoes epimerisation (Lobry de-Bruyn Van Ekenstein rerrangement) to give an aldehyde (D-glucose/D-mannose).

Throughout the equilibrium, keto-enol tautomeism takes place.
