Question

Assertion (A): HCI is produced by the reaction of hydrogen and chlorine in diffused sunlight.

Reason (R): This reaction is explosive in sunlight.

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

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(1)

Explanation:

Hydrogen reacts with chlorine in diffused sunlight to form hydrogen chloride (HCl). Therefore, the Assertion (A) is true.

The reaction between hydrogen and chlorine is explosive in direct sunlight, so diffused sunlight is used to control the reaction. Therefore, the Reason (R) is true and correctly explains the Assertion.

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