can some one answer this for me1).Using named examples of solids with a Giant Metallic, Covalent, Ionic and Simple Molecular Structure, explain differences in electrical conductivity in terms of mobile charged particles carrying current, and differences in melting point in terms of strength of inter-particle forces

2.) Using named examples of solids with a Giant Ionic and Simple Molecular Structure, explain differences in solubility in terms of polarity of water and attraction of solute for solvent.

For the conductivity always remember that only mobile charged particles can conduct electricity
For solubility - like dissolves like
polar compounds are soluble in polar solvents and non-polar are soluble in non-polar solvents.
