Solution
An aqueous solution of copper sulphate, sodium hydroxide, potassium sodium tartarate is called the Fehling’s reagent.
Fehling’s reagent is used for reducing sugars and not specific for aldehydes.
Fructose is a reducing sugar with one free ketone group. It reduces Fehling’s solution giving brick red precipitate.
Fructose under alkaline condition converted to glucose and mannose by keto-enol tautomerism giving positive to Fehling’s solution.
