CBSE Class 11-science Answered
out of which MgO and NaCl have higher Lattice Enthalpy and why?

Expert Answer
The lattice energy of an ionic compound is the enthalpy change which occurs when one mole of an ionic compound dissociates into its ions in gaseous state.
More ionic is a compound, stronger would be the ionic bond and more would be the lattice enthalpy.
In MgO, the ionic bond is stronger than in NaCl because of more charge on the ionic species in the former (Mg+2 and O2- as compared to Na+ and Cl-). Because of this the ionic interactions are stronger in MgO than in NaCl. As a result the lattice enthalpy of MgO is higher than NaCl.
