Fructose reduces Tollen's reagent due to

Options

  1. Aasymmetric carbons
  2. Bprimary alcoholic group
  3. Csecondary alcoholic group
  4. Denolisation of fructose followed by conversion to aldehyde by base

Correct answer

D. enolisation of fructose followed by conversion to aldehyde by base

Step-by-step solution

In aqueous solution, fructose is enolised and then converted into aldehyde in basic medium. All aldehydes generally reduce Tollen's reagent, thus fructose also reduces Tollen's reagent.
