Vedclass · Answer

(D) $1$. Glucose is an aldohexose,which is a correct statement as it contains an aldehyde group and six carbon atoms.$2$. Glucose exhibits mutarotation due to the equilibrium between its $\alpha$ and $\beta$ anomeric forms in solution.$3$. Reaction of glucose with $HI/\Delta$ leads to the reduction of the carbon chain to $n-hexane$,confirming the presence of a straight chain of six carbons.$4$. Cellulose is a linear polymer of $\beta-D$-glucose units linked by $\beta(1 	o 4)$ glycosidic bonds,not $\alpha-D$-glucose. Therefore,the statement that $\alpha-D$-glucose is the monomer of cellulose is incorrect.
