Bond Energy
1PRACTICE PROBLEM
In bonds formed, the lone pairs of electrons on one atom repel the lone pair of electrons on the other atom in the bond. Consider the following diatomic species: F2 (155 kJ/mol), Cl2 (242 kJ/mol), Br2 (193 kJ/mol), and I2 (151 kJ/mol). Why is the bond energy of F2 smaller than expected?
