Cellulose upon acetylation with excess acetic anhydride / H ₂ SO ₄ (catalytic) gives cellulose triacetate whose structures is

Correct answer

0

Step-by-step solution

Cellulose is a straight chain polysaccharide composed of D-glucose units, which are joined by -glycosidic linkages between C -1 of one glucose and C-4 of the next glucose. In one, unit only three hydroxy groups are free to form acetate, that's why called cellulose triacetate
