Question

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):

Assertion: Water is one of the best solvent.

Reason: H-bonding is present in water molecules.

Options

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

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

• If the Assertion is correct but Reason is incorrect.

• If the Assertion is incorrect and Reason is correct.

Answer 1

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

Explanation:

Although both assertion and reason are true, reason is not the correct explanation for assertion.

Water is an excellent solvent due to its high dielectric constant. Because of the high dielectric constant value, the electrostatic force of attraction between the ions decreases, causing the ions to separate and eventually be solvated by the solvent molecules.
