The bond energies for ionic compounds, such as Li–Br (807 kJ/mol) and NaCl (787 kJ/mol), are significantly higher than those of covalent bonds like H–H (432 kJ/mol) and C–O (358 kJ/mol). This trend indicates that ionic bonds, which involve the electrostatic attraction between oppositely charged ions, typically require more energy to break than covalent bonds, where electrons are shared between atoms. The stronger attractive forces in ionic compounds arise from the full charges of the ions, whereas covalent bonds involve only partial charges. Consequently, this difference in bond energies largely reflects the nature of the bonding: ionic bonds are stronger due to their ionic character and the resulting lattice structures, leading to greater stability and higher bond energies compared to covalent bonds.
