Statement I ; Fructose does not give positive Tollen's test

Statement II ; Fructose is a reducing sugar

Though fructose is a ketose it is a reducing sugar;

It gives positive Tollen's,Fehling's and Benedict's test;

All the above reagents oxidize the aldehyde group to carboxylic acid group in alkaline medium;

Fructose in alkaline medium undergoes reversible isomerisation(Lobry-debruyn-van ekenstein rearrangement) to give a mixture of glucose,fructose and mannose.

$\therefore$fructose gives postive Tollen's,Fehling's and Benedict's test;
