I hope somebody out the can help with the answers Outline the principles of a theory that is used to describe the shapes of simple covalent molecules. Use the theory to explain the shapes of the following molecules: a) BH3 b)PCl3 c)SiH4 d)H2S And my darlings; In terms of structure and bonding explain the difference in physical properties between diamond and graphite. A Big thank you to anybody that can help me! x

Does anybody know the answers to these questions? Benzene, Magnesium chloride, Potassium iodide, Sodium chloride, Hydrogen Chloride, Tetrechloridemethane. List the compounds whose solids probably have simple molecular crystal structures. List the compounds whose solids probably have ionic crystal structures. Wich of the compounds would you expect to conduct elctricity when molten? What does your answer suggest about the kind of particles which may be present in the crystals of these compounds? A big thankyou to anybody that can answer these for me x
