MCQ

Fructose reduces Tollen's reagent due to

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

✓

Answer

Correct option: D.

enolisation of fructose followed by conversion to aldehyde by base

d
Fructose is a ketose, in the presence of a base, it is converted into-a mixture of glucose and manmose in an enolisation followed by conversion to aldehyde, both of which contain the $-CHO$ group and hence reduce Tollen's
reagent to give silver mirror test.
