Why does fructose reduce Fehling's solution?

*Hysteria X*

is it because of the keto group it has? what generally reduces fehlings solution and tollens reagent??

You must know which group in organic analysis uses Tollen's and Fehling's solution as confirmatory test.

Actually, fructose in aqueous solution is not just fructose. It changes its form, being under kinetic equilibrium with its other forms (try to guess), which in turn are responsible for those confirmatory tests.
