Why or why not?Electron pairs, whether they are shared between two nuclei in a bond or are lone pairs, will repel andarrange themselves as far away from each other as possible in three dimensional space. A central atomwith two shared and two lone pairs will have the same electron pair geometry as a central atom withfour shared pairs. However, the geometry of the molecule as we "sense" it is determined by the nuclei.We do not "see" lone pairs. Therefore the geometry of molecules with lone pairs will be different thanthose with just shared electron pair.A multiple bond between two atoms means that there is more electron density between those nuclei.For geometric considerations, the double or triple bond is treated like a single bond. A central atomwith two single and one double bond will arrange the electron pairs as if it has three electron pairsassociated with it.Complete Table 2 as you did for Table 1 keeping in mind lone pairs and multiple bonds.Determine the geometry of all electron pairs, called the electron pair geometry. We cannot seelone pairs when we image a molecule (we Asee@ nuclei by x-ray diffraction techniques) so themolecular geometry is determined by taking the electron geometry and removing the lone pairs6.101Exploring the Chemical World, PGCC, 2003

The molecular ion S3N3 has the cyclic structure All SN bonds are equivalent. (a) Give six equivalent resonance hybrid Lewis diagrams for this molecular ion. (b) Compute the formal charges on all atoms in the molecular ion in each of the six Lewis diagrams.

Show that this result is consistent with the overall +1 charge on the molecular ion.
