Question

Fructose reduces Tollen's reagent due to:

• A. asymmetric carbons
• B. primary alcoholic group
• C. secondary alcoholic group
• D. enolisation of fructose followed by conversion to aldehyde by base

Answer 1

The correct option is D enolisation of fructose followed by conversion to aldehyde by base

In aqueous medium, fructose is enolised and converted into aldehyde in basic medium. Generally all aldehydes reduce Tollen's reagent, thus fructose can also reduces Tollen's reagent.
