Witryna6 mar 2024 · The more iodine is attached, the higher is the iodine value, and the more reactive, less stable, softer, and more susceptible to oxidation and rancidification is the oil, fat, or wax. WitrynaThe data above indicate that the halogen radicals have different reactivity; fluorine is the most reactive, and iodine is the least reactive. The iodine radical is very unreactive with overall “+” enthalpy, so iodine does not react with alkane at all. On the other side, the extreme high reactivity of fluorine is not a benefit either.
