Free Radicals
are molecules or ions that have an unpaired electron. They tend to
be very reactive and are thought to contribute to the aging
process. A "dimer" forms when two of the same molecules combine (dimerize). |
Draw a Lewis structure for each of the substances below and
indicate which are free radicals. For a free radical the unpaired
electron goes on the least electronegative element, which is
usually the central atom.

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: hy NO2 NO O O O2 3 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...
