lonic Compound Melting Polnt (C) MGF2 1263 MgBr2 711 CuCl 430 CuCl, 620 Which of the following statements is consistent with the melting point data shown in the table? For a given cation, ionic compounds with smaller anions have a higher melting point. lonic compounds that contain cations with al" charge have a higher melting point than do ionic compounds that contain cations with a 2 charge. C lonic compounds with the smallest difference in the electronegativities of the atoms have the highest melting point. The smaller the charge of the ions in an ionic compound and the larger the cation, the higher the melting point.
