Glucose and fructose

Vedclass · Answer

(B) Sugars like glucose,fructose,and mannose form identical osazones when treated with excess phenylhydrazine. This occurs because the structural differences between these sugars exist only at the $C-1$ and $C-2$ positions. During the formation of osazone,these two carbon atoms are involved in the reaction,resulting in the same phenylosazone structure for all three sugars.
