Question:

(a) Figure 17.7 showed the structure of [(AgI2)n]n+ and an MO scheme for the bonding. The bonding may also be represented using the valence bond approach. The diagram below illustrates the positive charge localized on Ag+ centres. Use this as a starting point to draw a set of resonance structures which illustrate I2 acting as a charge donor. How does this compare with a VB scheme for the bonding in [I5]+?

(b) When I2 reacts with SbF5 in liquid SO2, the compound [I4][Sb3F14][SbF6] is formed. Explain what happens in this reaction, and draw the structures of the ions present in the product. Assign oxidation states to each atom in the product.


Figure 17.7.
