For two ionic solids, `CaO` and `KI`, which of the following statements is false?

A

Lattice enthalpy of `CaO` is much higher than that of `KI`.

B

`CaO` has high melting point.

C

`KI` has low melting point.

D

`KI` is soluble in benzene.

Text Solution

Verified by Experts

The correct Answer is:
D
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 bezene.
