Fluorine bond dissociation energy

WebJul 16, 2024 · Lattice energies calculated for ionic compounds are typically much larger than bond dissociation energies measured for covalent bonds. Whereas lattice energies typically fall in the range of 600–4000 kJ/mol (some even higher), covalent bond dissociation energies are typically between 150–400 kJ/mol for single bonds. WebOct 27, 2008 · If I recall correctly, the silicon-fluorine single bond is the strongest single-bond strength for any pair of atoms. I would be hard-pressed to say the effect is completely that of a silylium Lewis acid but is probably more due to the extreme silicon-fluorine affinity. Roger Simon Waldron, Ark.
