Which statement best explains why the lattice energy of MgO is more exothermic than that of NaCl?
Select one option.
A
MgO has weaker electrostatic attraction because its ions are larger
B
NaCl has stronger electrostatic attraction because it contains more ions per formula unit
C
MgO has higher ionic charges and shorter interionic distance, so electrostatic attraction is much stronger
D
MgO has significant hydrogen bonding that stabilises its lattice
E
NaCl forms a giant covalent lattice while MgO forms a giant ionic lattice
