Document Summary
Homo iytic bond cleavage leads to the formation radicals of. B. reactive owe to unpaired highly e- short-lived can be made heat or light through weak. No of lone pairs , bonds such as o_o or x using the more unstable the molecule. Orbital are in sp the hybridized un hybridized with this allows chiral centres to give both the. R1s formation because the e- can bottom attack from the top or. Chlorine radicals are reactive that they arent even selective between. 5/2. 11 . leads to a mixture of mono and polychlorinated products. Bromine radicals are much less reactive more selectivity. Iodine radicals are even less reactive and dont even react with alkanes. Formation the of initial radical: propagation : (3) Halogen atom is most useful only products are possible . Fluorine chlorine too reactive no selectivity too reactive no selectivity. Iodine endothermic so no rxn "s take place. Macromolecules made up of repeating sub - units.
