VSEPR Worksheet Briefly describe the primary ideas behind VSEPR theory. 1) Electrons are negatively charged and like repels like so the atoms in a molecule will likely be as far away from each other as possible. 2) For each of the following compounds, a Lewis structure, determine the bond angles and molecular shapes for all atoms: a) BI3 120 o .. .. I .. .. B I .. .. .. 120 o .. I .. b) CH4 120 o trigonal planar H 109.5 o H C H 109.5 o H c) tetrahedral NF3 107.5 o d) F .. .. .. 107.5 o .. .. .. .. F .. .. F N .. 107.5 o C2H2 180 o H C C H trigonal pyramidal
