Document Summary
Sample exam 2 will be this friday instead of canvas hw. All ta"s will run exam reviews next week. Vespr uses regions of high e- density (rhed) 1 single bond = 1 lone pair = 1 mutley bond = 1 rhed. # of rhed around central atom detriment e- arrangement (geometry) Molecules structure (3d shape) if n lone pairs but if lone pairs the molecular shape is based on where the atoms are and lone pairs do not count. Exl pf3 4 rhed, 1 lone pair = trigonal pyramidal. Tetrahedral e- artment no lone mapres and a tetrahedral molecular shape. For more complicated molecules that are not just a central atom surrounded by other atoms, we just apply the same principles to each central atom in turn. Tetrahedral e- arrangement and no lone pairs. Tetrahedra muscles shape are touch each carbon. En tells whether bond is polar, nonpolar, or. Overall net dipole is sum of dipole moments of ionic.
