Answer 2

Answer:

$MgCl_{2}$ has more lattice energy.

Explanation:

• Lattice energy is the energy given off when one mole of gaseous cations and one mole of gaseous anions form one mole of ionic crystal (Δ$H_{lat}$).
• The amount of lattice energy released depends on the following factors:

1. Charge size- The greater the charge on either cation or anion, the greater the production of lattice energy.
2. Inter-ionic distance- Lattice energy is inversely proportional to the inter-ionic distance between the ions. the smaller the distance, the more will be the lattice energy as more force of attraction will be acting.

• In $MgCl_{2}$, $Mg^{2+}$ has $+2$ charge and $Cl^{-}$ has $-1$ charge, while in $NaF$, $Na^{+}$ has $+1$ charge and $F^{-}$ has $-1$ charge. We can clearly see that the former cation has bigger charge- $Mg^{2+}$; hence, the lattice energy of $MgF_{2}$ is more.
