3) The energy required to dissociate an ionic solid into gaseous ions is known as the lattice energy. Sodiumchloride, NaCl, has a lattice energy of 787.3 kJ/mol. Sodium oxide, Na2O has a lattice energy of 2564 kJ/mol.Which explanation best accounts for this difference?a. Chloride has a smaller ionic radius than oxide, resulting in a lower lattice energy.b. Chloride cannot form hydrogen bonds.c. There are two sodium ions in the chemical formula, meaning there are more ions that need tobecome a gas.d. Oxygen has a -2 charge, whereas Cl has a -1 charge. This results in a stronger attraction for Na2O.
