$MgO$

Vedclass · Answer

(C) The strength of an ionic bond is directly proportional to the Lattice Energy $(LE)$,which is given by the relation $LE \propto \frac{q_1 q_2}{r}$,where $q_1$ and $q_2$ are the charges on the ions and $r$ is the internuclear distance.Comparing the given compounds:$NaCl$: Charges are $+1, -1$.$Na_2O$: Charges are $+1, -2$.$MgF_2$: Charges are $+2, -1$.$MgO$: Charges are $+2, -2$.Since $MgO$ has the highest product of charges $(|(+2) 	imes (-2)| = 4)$ and relatively small ionic radii,it possesses the highest lattice energy and thus the strongest ionic bond.
