Solution:

Cellulose is a linear polymer of

\beta\text{-D-}

glucose in which

C_1

of one glucose unit is connected to

C_4

of the other through

\beta\text{-D}

glucosidic linkage. It does not undergo hydrolysis easily. However on heating with dilute

\mathrm{H}_2\mathrm{SO}_4

under pressure. It does undergo hydrolysis to give only

\mathrm{D}\text{-}

glucose.

(\mathrm{C}_6\mathrm{H}_{10}\mathrm{O}_5) n + n \mathrm{H}_2\mathrm{O} \overset{\mathrm{H}^+}{\longrightarrow} \underset{\text{D-Glucose}}{n\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6}
