Of 0.1 molal solutions of glucose and NaCl respectively which one will have a higher boiling point?

Answer:

In the same volume of water,0.1 molar of NaCl will have a greater boiling point elevation, as boiling point elevation is a colligative property which depends on the relative amount of the constituent and not on their identity.

Since more ions will be produced by NaCl (ionic compound) than glucose (covalent compound)
as there are more componets part in the NaCl molecule so the NaCl will have more boiling point.
