Document Summary

Day 9 notes: highly reactive chemical species with one or more unpaired electrons, seek out another electron to form a pair, create another radical (chain reaction) Free radicals and ozone destruction: the formation of free radicals from cfcs destroy ozone, man-made substances with long atmospheric lifetime, cheap, non-toxic, non-flammable-made air conditioning readily accessible. What"s next: the montreal protocol called for the elimination of cfc"s, these are all things that have been developed instead of using hydrofluorocarbons, although the lifetime decreases, they all have some other bad qualities. Day 9 notes: a molecules shapes plays a large role in how the molecules behave, to visualize a molecule"s shape. First need to convert the formula to a lewis structure. Remember: lewis structures do not indicate molecular shapes, they only show connectivity! Molecular shape: the shapes of compounds can be different even though their molecular formulas are similar why, because lone pairs affect shape.
