Identify which of these molecules has the highest boiling

Last updated: 8/5/2022

Identify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force. H₂O, KCI, CO₂ KCI has the highest boiling point Boiling point is in the order KCI>H2O>CO2 in KCI inter molecular force is ionic bond. That is formed by compleate tranfer of electrons. Hence break the bond is very difficult. Hence boiling point is higher. H2O has hydrogen bond hence its boiling point is higher than that of CO2)
