WebApr 2, 2024 · The presence of reactive chlorine species in UV-Cl can be useful in removing contaminants that are resistant to hydroxyl radicals. Other matrix components such as Br– and HCO 3 – can scavenge with HO. and reactive chlorine species and form secondary radicals such as reactive bromine species and CO 3 –. WebThe above said positions (ortho and para) are the most reactive towards an electron-poor electrophile, thus promoting electrophillic substitution reaction. The methyl group hence makes it around 25 times more reactive than benzene hence making its nitration more easier than that of benzene.
