Choose the incorrect statement regarding Cellulose.
- A It does not reduce Fehling's solution nor Tollen's reagent.
- B It is a straight chain polysaccharide made of \(\beta-\mathrm{D}\)-glucose units.
- C The \(\beta\)-glycosidic linkages are between \(\mathrm{C_1}\) of one Glucose unit and \(\mathrm{C_5}\) of the next Glucose unit.
- D On heating with dil. \(\mathrm{H}_2 \mathrm{SO}_4\) under pressure, Cellulose gets hydrolysed to D-Glucose.
Answer & Solution
Correct Answer
(C) The \(\beta\)-glycosidic linkages are between \(\mathrm{C_1}\) of one Glucose unit and \(\mathrm{C_5}\) of the next Glucose unit.
Step-by-step Solution
Detailed explanation
Cellulose is a linear polysaccharide composed of \(\beta\)-D-glucose units linked together by \(\beta\)-glycosidic linkages. The \(\beta\)-glycosidic linkage in cellulose occurs between the \(\mathrm{C_1}\) carbon of one \(\beta\)-D-glucose unit and the \(\mathrm{C_4}\) carbon…
