Oxidation state ––> measure of the electron budget of an element + electron deficit electron surplus For most compounds: O: -2 (-1 per bond ) H : + 1 important exceptions: O in OH·, H O O·, RC O O·,H 3 CO·, H 2 O 2 : -1 neutral elements (N 2 , O 2 , C°): 0 Example of N: Example of C: N 2 CH 4 N O · H 3 CCH 3 NO 2 · RHC=CHR NO 3 H 2 CO HNO 3 C 6 H 12 O 6 C (s) (soot, graphite, diamond) RHCO CO 2

Photochemical smog A. General process of smog formation: VOCs (volatile organic compounds) + NO· + sunlight + stagnant air mass –––––––––––––––––––––––––––– = O 3 , H 2 O 2 , HNO 3 , PAN ( p eroxy a cetyl n itrate) VOCs: volatile -low boiling point, evaporate readily in air organic compounds -mainly hydrocarbons (alkanes, alkenes, alkynes, aromatic hydrocarbons) –––––––––––––––––––––––––––––––––––––––––––––– Overall, smog formation involves the oxidation of organic C and N
