Question

For two ionic solids $CaO$ and $KI$ which of the following statement(s) 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. $CaO$ is not soluble in benzene

Answer 1

Answer: (D)

$CaO$ is not soluble in benzene

Lattice enthalpy of $CaO$ is much higher than that of $KI$. $CaO$ has high melting point. $KI$ has low melting point. $CaO$ is not soluble in benzene, actually $CaO$ is soluble in benzene.
