WebYou may wonder why we don’t just react our organic radical with another Br radical, right? The reason for this is because we make a very low concentration of those Br radicals in the initiation step. So, it’s highly unlikely that our organic radical meets … WebJun 25, 2000 · A free radical can react with another free radical, but more often it reacts with a stable, evenly paired molecule. It does so by (1) donating an electron to the molecule, (2) removing an electron from the molecule, (3) removing a group of atoms from the molecule, or (4) adding itself to the molecule.
