U NIT 2 M ODULE 3: P REDICTING G EOMETRY 3-03 R ADICAL SPECIES (AKA , FREE RADICALS )HAVE AN ODD NUMBER O F UNPAIRED ELECTRONS AND CAN BE EITHER CHARGED OR NE UTRAL ATOMS . YOU VIOLATE THE O CTET R ULE WHEN T HERE ARE MORE THAN 8 SHARED ELECTRONS 1. Electron Repulsion a. The molecular geometry of a certain molecule is driven by the idea that electrons and the domains they are in try to stay as far apart from one another that they can i. This is called the VSEPR theory 2. Larger Molecules a. When dealing with larger molecule s, you can identify the geometry around different central atoms in the molecule. i. This isn’t hard. All that is necessary to do is find central atoms (atoms with other atoms surrounding it, i.e. NOT the atoms at the end of the molecule) and use VSEPR to def ine the geometry. b. Line Structures i. Each sharp angle or line end indicates a carbon atom. These carbons are always bonded to hydrogens. Make sure the carbon only has 4 bonds. 3. Functionality a. What are called functional groups can determine properties of a mol ecule. i. Functional groups are pieces of a larger molecule , and these are determined through the molecular composition b. “R” group is the rest of the molecule that is attached to the specific functional group. 2
