As fructose undergoes Lobry de Bruyn-Van Ekenstien rearrangement.It is concluded that fructose with Ketone group also could reduce fehling''s reagent,tollen''s reagent etc.

Lobry de Bruyn-Van Ekenstien rearrangement:-It is a reversible isomerism,to give a mixture of D-glucose,D- fructose and D-fructose.
