Ozone chemguide
WebOzonolysis is a method of oxidatively cleaving alkenes or alkynes using ozone ( O 3 ), a reactive allotrope of oxygen. The process allows for carbon-carbon double or triple bonds to be replaced by double bonds with oxygen. Webozone assessments the adopted value of et for global averaged ozone loss has been between 40 and 60 [WMO, 1995, 1999]. If a value of 100 were more appropriate, then the …

(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

They tend to be broken down in the lower atmosphere by reaction with hydroxyl radicals, OH. But even the molecules which reach the ozone layer obviously can't produce chlorine radicals - …
WebCFCl 2 + Cl The Cl and Br atoms can then destroy ozone molecules through a variety of catalytic cycles. In the simplest example of such a cycle, a chlorine atom reacts with an ozone molecule, taking an oxygen atom (forming ClO, chlorine monoxide) and leaving a normal oxygen molecule (O 2).The chlorine monoxide can then react with a second …
WebPhotochemical Smog.
