Question

nstructions: Complete each of the following problems to the best of your ability. Each question or part of a question) is worth 2 points. The points are all or nothing (no partial credit). 1) Free radicals are molecules that contain an unpaired electron. Free radicals are important in many environmentally significant reactions. For example, photochemical smog - smog that results from the action of sunlight on air pollutants - forms in part by these two steps: NO2 hy NO+0 O+O2O The product of this reaction, ozone, is a pollutant in the lower atmosphere. (Upper atmospheric ozone is a natural part of the atmosphere that protects life on Earth from ultraviolet light.) Ozone is an eye and lung irritant and also accelerates the weathering of rubber products. Rewrite the above reactions using the Lewis structures of each reactant and product. Draw all resonance structures for any compound that has resonance structures. Identify the free radicals

Answer 1

radical Х ХХ Xxx XX xx XX ох * Г . -ҳу Х .

Resonating structures → x x XX x x **

2 x C)

NO,NO_​​​2 and O_{​​​​​​3} are free radicals.
