Question

Assertion (A): Dehydration of carbohydrate is called charring.

Reason (R): After the dehydration of carbohydrates, carbon is left behind.

Options

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If both A and R are true, and R is the correct explanation of A.

Explanation:

When carbohydrates like cane sugar or glucose react with a strong dehydrating agent, the hydrogen and oxygen are completely removed as water. This chemical removal leaves behind a black, spongy mass of elemental carbon, which is why the dehydration process is explicitly called charring. Therefore, the reason directly explains why the reaction gets this specific name.
