8. (4 marks) Draw Lewis structures of the following compounds and name the central atom electron geometry and molecular geometry for each. Expand octets to reduce formal charge, if needed.

Show all lone pairs using the paired dots (••). If a molecule has more than one resonance structure of high significance, present just one. Show formal charges only if they are not zero. List all the ideal bond angles that apply in the compound with respect to the central atom (there may be more than one, depending on the structure).
