83 -- Considering the properties of water and hydrogen sulfide molecules, which statement is correct?
The difference in intermolecular attractive forces is the most important factor in the difference in their boiling points.
The difference in molecular structure is one of the most important factors determining the difference in boiling points of the two molecules.
The difference in atomic radii and molar mass of central atoms plays a role in determining the difference in boiling points of the two molecules.
The polarity difference of the two molecules, like the polarity difference of $\text{CS}_2$ and $\text{CO}_2$ molecules, plays no role in determining their boiling points.
