I was looking again at the periodic trends like Ionization Energy, Electron Affinity, Radius and so on. I understood all the general trends and the exeptions for these ones, but I can't fully understand the trends for Atomization Enthalpy/Energy.
Quoting my book ( Inorganic Chemistry - Atkins ) : "...
In this paper it is mentioned that
... octenidine can release iodine radicals from the
PVP complex, resulting in a tissue irritation as well as
strong brown to violet discolouration in the border areas.
but elsewhere I read that
... it turns out that ΔG > 0 for radical iodination.
Is it reall...
