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

A

Lattice energy of `CaO` is much larger than that of `Kl`

B

`Kl` is soluble in benzene

C

`Kl` has lower melting point

D

`CaO` has higher melting point

Text Solution

Verified by Experts

The correct Answer is:
B
KI is ionic compound, so it is not soluble in non-polar solvent (i.e. dipole moment (`mu`) for benzene =0)
