ketones donot respond to fehling test, but why does fructose, inspite of being a ketose respond to the reaction?

Expert Answer
D-Fructose rearranges to D-glucose in alkaline medium .this rearrangement is known as Lobry de Bruyn-Van Ekenstein rearrangement.
It is probably due to this isomerisation that fructose reduces fehling's solution in alkaline medium although it does not contain a -CHO group.
