Suppose that a molecule has four bonding groups and one lone pair on the central atom. Suppose further that the molecule is confined to two dimensions (this is a purely hypothetical assumption for the sake of understanding the principles behind VSEPR theory). Make a sketch of the molecule and estimate the bond angles.

The XeO3 molecule displays approximately which bond angles (in degrees)about the central Xe? VSEPR theory predicts which molecular structure (arrangement of bonded atoms about the central Xe atom) for XeO3?

Consider the Lewis Structure for the molecule, SeF4. On your own, make a sketch of the VSEPR shape, and use that to answer the following questions: :F: F-Se-F: :F: Part A What is the electronic geometry of this molecule? O trigonal bipyramidal O t-shaped O trigonal pyramidal O tetrahedral O square planar see-saw O octahedral O O O

What are the angles a and b in the actual molecule of which this is a Lewis structure? H H H C H a a = C b = ⁰ C H Note for advanced students: give the ideal angles, and don't worry about small differences from the ideal that might be caused by the fact that different electron groups may have slightly different sizes.
