Question

The reagent that can be used to differentiate an aldose and a ketose is :
Options
A Bromine water
Correct Answer
B Fehling's solution
C Tollens' reagent
D None of these
Correct Answer

Option A is the correct answer.

Detailed Explanation

Bromine water (Br2/H2O) oxidizes aldoses (to aldonic acids) but does not react with ketoses under mild conditions. Both aldoses and ketoses reduce Fehling's and Tollens' reagents (the latter after isomerization).

Hint

Which reagent differentiates aldoses from ketoses?
