I just took a kaplan PS section test and am reviewing a question that I can't wrap my head around. It says Solution A= 1 molality of NaCl and Solution B= 1 molality of glucose and asks which solutions have a higher boiling point and melting point.
I understand that NaCl has the higher boiling point since it dissolves into 2 particles however, they claim that glucose has a higher melting point?? It was my impression that ionic forces have very high melting points compared to covalent bonds. They simply say that the higher number of particles = higher boiling point and lower melting point.
Is this true? If it was freezing point I'd understand based on the same principle but i think this is wrong considering melting point.
