Cellulose upon acetylation with excess acetic anhydride/`H_(2)SO_(4)` (catalytic) gives cellulose triacetate whose structure is

A

C

D

Text Solution

Verified by Experts

The correct Answer is:
A

Cellulose is a linear-chain polysaccharide of `D-`glucose which is joined by `beta-`glycosidic linkage between `C-1` of one glucose and `C-4` of the next glucose. In one unit, only three `OH` groups are free to form triacetate, hence the structure is as given in `(a)`. That is why it is called cellulose triacetate.
