JEE MAIN - Chemistry (2022 - 29th July Evening Shift - No. 14)

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.

Both $$\mathbf{A}$$ and $$\mathbf{R}$$ are correct and $$\mathbf{R}$$ is the correct explanation of $$\mathbf{A}$$.

Both $$\mathbf{A}$$ and $$\mathbf{R}$$ are correct but $$\mathbf{R}$$ is NOT the correct explanation of $$\mathbf{A}$$.

$$\mathbf{A}$$ is correct but $$\mathbf{R}$$ is not correct

$$\mathbf{A}$$ is not correct but $$\mathbf{R}$$ is correct.

Explanation

Let's analyze the given statements:

Assertion A: "Amylose is insoluble in water." This statement is incorrect. Amylose is actually soluble in water, although its solubility is lower compared to other carbohydrates like amylopectin.

Reason R: "Amylose is a long linear molecule with more than 200 glucose units." This statement is correct, as amylose is indeed a linear polysaccharide made up of glucose units.

Given this information, the correct option is:

Option D: $\mathbf{A}$ is not correct but $\mathbf{R}$ is correct.
