(+) Glucose and (-) fructose can be differentiated by ?
(+) Glucose and (-) fructose can be differentiated by ?
Open in App
Solution
The correct option is C Bromine water
Bromine, a mild oxidising agent, oxidises only glucose (aldoses, in general) to gluconic acid. Tollen's reagent and Fehling solution being alkaline in nature cause isomerization of fructose to glucose hence both of them react with these reagents.
