O greater than ideal O ideal O less than ideal

It is possible to write a simple Lewis structure for the SO42- ion, involving only single bonds, which follows the octet rule. However, Linus Pauling and others have suggested an alternative structure, involving double bonds, in which the sulfur atom is surrounded by six electron pairs. (a) Draw the two Lewis structures. (b) What geometries are predicted for the two structures? (c) What is the hybridization of sulfur in each case? (d) What are the formal charges of the atoms in the two structures?

Among the following, which has the shortest bond and which has the longest: Li2, B2, C2, N2, O2?

Use Lewis structures and VSEPR theory to predict the electron-region and molecular geometries of (a) PSCl3. (b) SOF6. (c) [S2O4]2. (d) [TeF4]2. Note any differences between these geometries.
