Question

Assertion: Higher noble gases are soluble in water.

Reason: Noble gases are monoatomic in nature.

विकल्प

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

Explanation:

It is true that heavier noble gases like Xe are more soluble in water. However, this is not because they are monoatomic but due to dipole-induced dipole interactions with water molecules. The larger the noble gas atom, the more easily its electron cloud is polarised, increasing its solubility in water.
