Problem: List the following substances in order of decreasing boiling point CO2, Ne, CH3OH, KF 

FREE Expert Solution

We’re being asked to identify the compound with the highest boiling point among the given choices.


Compounds with strong intermolecular forces have high boiling points. This is because they require more energy to be able to break the bonds during the phase transition.


↑ intermolecular force = ↑ boiling poin


So, we need to identify which among the given compounds has the strongest intermolecular forces


The intermolecular forces arranged in decreasing order:


ion-ion < ion-dipole < dipole-dipole < H-bonding < induced dipole < dispersion force


We will do the following to determine the compound with the strongest intermolecular force

Step 1: Total valence electron

Step 2: Draw Lewis structure

Step 3: Determine the intermolecular force
