Vedclass · Answer

(B) Cellulose is a linear polymer of $\beta-D-glucose$ units.Each glucose unit in cellulose contains three hydroxyl $(-OH)$ groups (at $C_2$,$C_3$,and $C_6$ positions).In tri-nitro cellulose,all three hydroxyl groups are esterified with nitric acid $(HNO_3)$.Therefore,each glucose unit in tri-nitro cellulose has $0$ free $-OH$ groups,but the question asks for the number of $-OH$ groups present in the glucose unit structure before nitration or the number of sites involved in the formation of the tri-nitro derivative.Since it is 'tri-nitro' cellulose,all $3$ $-OH$ groups are substituted.

How many $-OH$ groups are present in each glucose unit of tri-nitro cellulose?
