Which of the following statements is/are incorrect?
1 Only (i), (ii) and (iii)
2 Only (iii), (iv) and (v)
3 Only iii
4 All except v
Explanation:
(c) Starch can hold iodine $\left( {{\text{I}}_{2}} \right)$ molecules in its helical secondary structure but cellulose being non helical, can not hold ${{\text{I}}_{2}}$. Thus, cellulose does not shows blue colour when treated with ${{\text{I}}_{2}}$.

Statement I: Plant cell walls are made of cellulose. Statement II: Paper made from plant pulp and cotton fibre is chitinic in nature.
1 Both Statement I and Statement II are incorrect
2 Statement I is correct but Statement II is incorrect
3 Statement I is incorrect but Statement II is correct
4 Both Statement I and Statement II are correct
Explanation:
(b) Statement II is incorrect. The correct statement is- Amylopectin is soluble in water while glycogen is insoluble in water.

Statement I: Inulin is a polymer of fructose.
Statement II: Starch forms helical secondary structure.
1 Both Statement I and Statement II are incorrect
2 Statement I is correct but Statement II is incorrect
3 Statement I is incorrect but Statement II is correct
4 Both Statement I and Statement II are correct
Explanation:
(a) Both statements I and II are incorrect. The correct statements are-
Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory glucose and laevorotatory fructose.
The laevorotation of fructose $\left( -{{92.4}^{\circ }} \right)$ is more than dextrorotation of glucose $\left( +{{52.5}^{\circ }} \right)$.
