Rank the substances HF,CCl4,KCl and NH3 from lowest to highest melting point. Explain your reasons in terms of intermolecular and intramolecular bonding. -Draw Lewis and/or VSEPR shapes for each. -Show EN for all bonds -indicate vectors and/or Net Vectors -indicate polarity of Intramolecular bond -indicate the Intermolecular forces For CCl4 and NH3 draw the full electron configurations for each atom in an Energy level diagram. Show the electron configuration of hybridization of the central atoms (C and N) to explain the VSEPR shape
