Fructose reduces Tollen's reagent due to
- A primary alcoholic group
- B secondary alcoholic group
- C enolisation of fructose followed by conversation to aldehyde by base
- D asymmetric carbon atoms
Answer & Solution
Correct Answer
(C) enolisation of fructose followed by conversation to aldehyde by base
Step-by-step Solution
Detailed explanation
Tollen's reagent is \(\left(\mathrm{AgNO}_3+\mathrm{NH}_4 \mathrm{OH}\right)\) and it enables basic medium. Fructose is a keto-hexose, still it can reduce Tollen's reagent. Because in basic medium, it undergoes epimerisation (Lobry de-Bruyn Van Ekenstein rerrangement) to give an…
