Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Amylose is insoluble in water. Reason R : Amylose is a long linear molecule with more than 200 glucose units. In the light of the above statements, choose the correct answer from the options given below. (1) Both A and R are correct and R is the correct explanation of A. (2) Both A and R are correct and R is NOT the correct explanation of A. (3) A is correct but R is not correct. (4) A is not correct but R is correct.

1. Both A and R are correct and R is the correct explanation of A.
2. Both A and R are correct and R is NOT the correct explanation of A.
3. A is correct but R is not correct.
4. A is not correct but R is correct.

Correct answer: A is correct but R is not correct.

Solution

Amylose is indeed insoluble in water due to its helical structure, which limits its interaction with water molecules. However, the assertion that it is a long linear molecule with more than 200 glucose units does not directly explain its insolubility, as other factors like hydrogen bonding and molecular structure also play a role.
