Question

Statement-1: LiF and CsI have low solubility in water.
Statement-2: Both have high lattice enthalpy.
A. Statement-1 is True, Statement-2 is True. Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer 1

Correct Answer - C
The low solubility of LiF in water is due to its high lattice enthalpy whereas low solubility of CsI is due to smaller hydration enthalpy of its two ions.
