Question

86. For two ionics solids CaO and KI, identify the
wrong statement among the following.
(1) CaO has high melting point
(2) Lattice energy of CaO is much larger than that
of KI
(3) Kl has high melting point
(4)Kl is soluble in benzene

I need explanation​

Answer 1

Answer:

(3)

Explanation:

Due to lower lattice enthalpy of KI as compared to CaO, the melting point of KI is lower than that of CaO. KI is ionic, so insoluble in benzene.
