- (a) Predict the geometry of the SbCl52 ion, using the VSEPR method. (b) The ion SbCl63 is prepared from SbCl52 by treatment with Cl . Determine the steric number of the central antimony atom in this ion, and discuss the extension of the VSEPR theory that would be needed for the prediction of its molecular geometry.Discuss the nature of the bonding in the nitrite ion (NO2) . Draw the possible Lewis resonance diagrams for this ion. Use the VSEPR theory to determine the steric number, the hybridization of the central nitrogen atom, and the geometry of the ion. Show how the use of resonance structures can be avoided by introducing a de-localized MO. What bond order does the MO model predict for the NO bonds in the nitrite ion?Discuss the nature of the bonding in the nitrate ion (NO3) . Draw the possible Lewis resonance diagrams for this ion. Use the VSEPR theory to determine the steric number, the hybridization of the central N atom, and the geometry of the ion.

(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. (c) Determine the charge on each atom in the polyatomic ion, assuming that the true distribution of electrons is the average of the six Lewis diagrams arrived at in parts (a) and (b). (d) An advanced calculation suggests that the actual charge resident on each N atom is 0.375 and on each S atom is +0.041 . Show that this result is consistent with the overall +1 charge on the molecular ion.Assign formal charges to all atoms in the following Lewis diagrams. (a) SO42 (b) S2O32 (c) SbF3 (d) SCN
- A certain atom in a molecule has a formal charge of 0 and when illustrated in acovalent bonding, has one single bond and three lone pairs. The atom is most likely to be found in:Alkali metalsAlkaline earth metalsBoron familyCarbon familyNitrogen familyChalcogensHalogensNoble/Inert gasesTransition metalsUsing the information provided, it is impossible to determineSulfuric acid is prepared by oxidizing sulfur to sulfur dioxide and then to sulfur trioxide. Although sulfur trioxide reacts with water to form sulfuric acid it forms a mist of find droplets of H2 S04 with water vapor that is hard to condense. Instead sulfur trioxide is first dissolved in 98% sulfuric acid to form oleum. On treatment with water concentrated sulfuric acid can be generated. Write equations for all the steps and draw Lewis structures of sulfuric acid and oleum.for the carbonate CO32-, draw all the resonances structures, Identify which orbitals overlap to created bond
