The bent shape of the molecules leads to gaps in the hydrogen bonding network of ice. 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 is the diameter of the capillary tube? How does the boiling of a liquid differ from its evaporation? a. dipole-dipole rejections The coordination number, therefore, is eight.

Polarization separates centers of charge giving. In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. Suggest an explanation. $\ce{CO2}$, $\ce{CH4}$, and $\ce{N2}$ are symmetric, and hence they have no permanent dipole moments. Note that elecronegativity values increase from left to right and from bottom to top on the periodic table. a. ion-dipole Which has a higher boiling point, $\ce{I2}$ or $\ce{Br2}$? Substance D is soft, does not conduct electricity, and has a melting point of 185 C. Thus, London dispersion forces are strong for heavy molecules. You can have all kinds of intermolecular forces acting simultaneously. Select one: Which of the following elements reacts with sulfur to form a solid in which the sulfur atoms form a closest-packed array with all of the octahedral holes occupied: [latex]\ce{Li}[/latex], [latex]\ce{Na}[/latex], [latex]\ce{Be}[/latex], [latex]\ce{Ca}[/latex], or [latex]\ce{Al}[/latex]?
