Vedclass · Answer

(D) Glucose is an aldohexose $(C_6H_{12}O_6)$.When heated with $HI$,it undergoes reduction to form $n-hexane$,confirming the presence of a straight chain of $6$ carbon atoms.It reacts with hydroxylamine $(NH_2OH)$ to form an oxime,confirming the presence of a carbonyl group.However,glucose exists in a pyranose structure (a $6$-membered ring) in its cyclic form,not a furanose structure (a $5$-membered ring). Fructose exists in a furanose structure.Therefore,the statement that glucose contains a furanose structure is incorrect.

List-$I$ (Reaction of glucose with)	List-$II$ (Product formed)
$A$. Hydroxylamine	$I$. Gluconic acid
$B$. $Br_2$ water	$II$. Glucose pentaacetate
$C$. Excess acetic anhydride	$III$. Saccharic acid
$D$. Concentrated $HNO_3$	$IV$. Glucoxime
