WebAug 21, 2024 · For F 2 2) is less than for Cl 2 but since the energy needed to break the F-F bond is also less and the hydration more, the total energy drop is much greater. In spite of their lower atomization energies, Br 2 and I 2 are weaker oxidizing agents than Cl 2 and this is due to their smaller Δ EA H 1 and smaller Δ hyd H°. WebThe high reactivity of acyl phosphates is due mainly to the ability to form complexes with magnesium ions. The magnesium ion acts as a Lewis acid to accept electron density from the oxygen end of the acyl carbonyl bond, thus greatly increasing the degree of partial positive charge - and thus the electrophilicity - of the carbonyl carbon.

Why does fluorine have a higher ionization energy than bromine?

WebAnswer (1 of 3): The F atom is a free radical (has an unpaired electron) so it is a very reactive species like all free radicals. F2 is covalently single bonded with no unpaired electrons so it is clearly less reactive than a single F atom radical. However, F2 has the lowest bond energy of the ... WebThe reaction is believed to be bimolecular: NO(g)+F2(g)→NOF(g)+F(g) where NO is a free radical.
