Answer
Highest: Triple bonds and short, highly polar bonds (e.g., C≡N, H–F). Lowest: Single bonds between large atoms (e.g., I–I, Cs–I).
Explanation
1. Identify factors affecting bond energy Bond energy increases with stronger attractions: higher bond order, smaller atomic radii, and greater electronegativity differences. 2. Highest bond energy types Triple bonds (e.g., C≡N, N≡N) and bonds involving small atoms (e.g., H–F) have highest energies due to strong attraction and short bond length. 3. Lowest bond energy types Single bonds between large atoms (e.g., I–I) have lowest energies due to weak attraction and long bond length.
