1. The problem statement, all variables and given/known data What are the bond angles of TeCl4 2. Relevant equations none 3. The attempt at a solution The electronic geometry should be Trigonal Bipyramidal The molecular geometry should be See-Saw shaped (Steric Number 5, One lone pair) I know the angles are less than those of a trigonal bipyramidal shape with 5 bond pairs (90° and 120°) but I dont know what the angles are for the see-saw shape. Also, the VSEPR model only provides bond angles for structures with max bond pairs (for example, the steric number is 5 with five bond pairs). Does anyone know how you would determine the bond angle if there were lone pairs? Or is that only determined by experimental evidence Thanks!
