WebOct 12, 2024 · The solid consists of discrete chemical species held together by intermolecular forces that are electrostatic or Coulombic in nature. This behavior is most obvious for an ionic solid such as NaCl, where the positively charged Na + ions are attracted to the negatively charged Cl − ions. WebSolution: A) Lattice energy of CaO is much higher than that of KI. True because CaO is covalent in nature where as KI is ionic. B) KI is soluble in benzene.False because KI is ionic compound so it is not soluble in non polar solvent. C) CaO has high m.pt.True because the size of Ca is less than K.
