$Glucose$ and $fructose$

Vedclass · Answer

(A) When $glucose$,$fructose$,and $mannose$ react with an excess of phenylhydrazine,they form the same osazone derivative known as $glucosazone$.This occurs because the structural differences at the $C-1$ and $C-2$ positions are lost during the formation of the osazone,resulting in an identical phenylhydrazone structure for these three sugars.$Glucose$ ($C-1$ aldehyde,$C-2$ hydroxyl),$fructose$ ($C-1$ hydroxyl,$C-2$ ketone),and $mannose$ ($C-1$ aldehyde,$C-2$ hydroxyl with different configuration) all yield the same $glucosazone$ product.

Which of the following set of molecules give the same osazone when reacted with an excess of phenylhydrazine?
