Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The incorrect order of lattice energy is NaCl > LiF as lattice energy of LiF is more than NaF
$\mathrm{L}\mathrm{E}\propto \frac{{\mathrm{q}}^{+}.{\mathrm{q}}^{-}}{{\mathrm{r}}^{+}+{\mathrm{r}}^{-}}$
A.$\mathrm{A}\mathrm{l}{\mathrm{F}}_3>\mathrm{M}\mathrm{g}{\mathrm{F}}_2$[Charge on cation]
B.$\mathrm{L}{\mathrm{i}}_3\mathrm{N}>\mathrm{L}{\mathrm{i}}_2\mathrm{O}$[Charge on anion]
C.$\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}<\mathrm{L}\mathrm{i}\mathrm{F}$[Size of cation and anion]
D. TiC > ScN [Charges on cation and anion].
