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