Quantum and VSEPR Review Assign the 4 quantum numbers for the highest energy electron of the central atom in ground state Draw an orbital fill diagram for the valence level of the central atom Write out the electron configuration of an external atom Draw a Lewis structure for the compound How many σ and π bonds are in the compound Using #2 and #4 determine the hybridization of the central atom. Identify any coordinate covalent bonds by circling them on the Lewis structure Determine the VSEPR shape (base shape and bonded atoms) and draw the 3D representation (dashes and wedges) Calculate ΔEN for all bonds Determine polarity of the compound Indicate the major IMF present in the compound Would you expect the compound to be soluble in water Order the compounds on the bench from predicted lowest melting point to highest
