The boiling point of [latex]\ce{CS2}[/latex] is higher than that of [latex]\ce{CO2}[/latex] partially because of the higher molecular weight of [latex]\ce{CS2}[/latex]; consequently, the attractive forces are stronger in [latex]\ce{CS2}[/latex]. e. hydrogen bonding, What intermolecular force is responsible for the fact that ice is less dense than liquid water? c) increases linearly with increasing temperature Discussion - The net result is rapidly fluctuating, temporary dipoles that attract one another (e.g., [latex]\ce{Ar}[/latex]).

The individual dipoles point from the \(\ce{H}\) atoms toward the \(\ce{O}\) atom. As a result, ice melts at a single temperature and not over a range of temperatures. What you have misunderstood is that there are no intermolecular forces between these ions, as number one the forces are not between molecules but ions, and number two if you break the bonds between a $\ce{Na+}$ and a $\ce{Cl-}$ ions, you have effectively broken an intramolecular bond . What does this suggest about the polar character and intermolecular attractions of the three compounds? Hence the forces are different, too.

Types of intramolecular forces of attraction Ionic bond: This bond is formed by the complete transfer of valence electron (s) between atoms. When all the liquid has vaporized, the tank pressure will drop as the cylinder continues to release gas: Yes, ice will sublime, although it may take it several days. The water molecules have strong intermolecular forces of hydrogen bonding. The electrostatic attraction between the partially positive hydrogen atom in one molecule and the partially negative atom in another molecule gives rise to a strong dipole-dipole interaction called a hydrogen bond (e.g., [latex]\ce{HFHF}[/latex]).
