Question

Why table salt, NaCl, has a higher melting point than glucose?

Answer 1

Answer:

Sodium chloride has a high melting and boiling point because :-

There are strong electrostatic attractions between the positive and negative ions, and it takes a lot of heat energy to overcome them. ... The sizes of the ions: If the ions are smaller they get closer together and so, the electrostatic attractions are greater.
