Both of these temperatures, of course, are completely wrong for an ionic compound - they are much too low. They suggest comparatively weak attractions between molecules - not strong attractions between ions.
WebThe reported melting point of ( R)-Tolterodine tartrate crystallized from 1,2-propylene carbonate is 489K (216°C) [17]. This value agrees with DSC data, which show a sharp endothermic event with an apex at 218°C ( Fig. 4 ). The DSC endothermic event at 216°C was also mentioned in the literature [19]. WebAnswer (1 of 5): Among the mentioned 4 compounds, SiCl₄ will have maximum covalent character. The extent of covalent character of ionic compounds is governed by Fajan’s rules. The rule concerned in this example is that the cation with the higher positive charge has greater covalent character than...
