WebThe most effective way to cleave alkene is to use ozone, O 3, through a two-step process. Alkene first reacts with ozone at very low temperature (-78°C) and then is treated with … WebThe new radical can react with a second ozone molecule to turn it into ordinary oxygen and regenerate a chlorine radical. (Note: There is an alternative reaction which can regenerate the chlorine radical: If you have used that one, that's fine. But whichever you have used, it makes sense to use the one expected by your examiners.) 6. a) Homogeneous

Each O atom has 6 valence electrons, for a total of 18 valence electrons. 3. Assigning one bonding pair of electrons to each oxygen–oxygen bond gives with 14 electrons left over. 4.
