Vedclass · Answer

(B) The formation of osazone involves the reaction of glucose with phenylhydrazine. Initially,the carbonyl group at $C-1$ reacts with phenylhydrazine to form a phenylhydrazone. Subsequently,the $C-2$ carbon atom undergoes oxidation to a carbonyl group,which then reacts with another molecule of phenylhydrazine to form the osazone. Thus,the $C-1$ and $C-2$ carbon atoms are involved in the process due to the oxidation of the $C-2$ hydroxyl group.

Only two carbon atoms of glucose participate in the formation of osazone because they undergo .......
