Q18 / 200 · Manipal (MET) 2011 · Chemistry

Complete hydrolysis of cellulose gives

  • A
    D-fructose
  • B
    D-ribose
  • Correct answer
    C
    D-glucose
  • D
    L-glucose

Solution

Cellulose is a polysaccharide, composed of D-glucose units which are joined by $\beta$-glycosidic linkages. On complete hydrolysis cellulose produces D-glucose. $\left(\mathrm{C}_6 \mathrm{H}_{10} \mathrm{O}_5\right)_n+n \mathrm{H}_2 \mathrm{O} \xrightarrow{\mathrm{H}^{+}} \underset{\text { D-glucose }}{n \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6}$

Hence, the correct answer is option: 'C'.
