Question

Assertion: LiF is less soluble in water

Reason: Lit has small size, thus it has very low hydration enthalpy.

(1) Assertion is true, Reason is true and Reason is correct explanation of Assertion

(2) Assertion is true, Reason is true and Reason is not correct explanation of Assertion.

(3) Assertion is true and Reason is false

(4) Assertion is false and Reason is true

Answer 1

Correct option is (3) Assertion is true and Reason is false

LiF is less soluble due to high value of lattice energy.

Li⁺ has small size and has very high hydration enthalpy.
