Explain why nonpolar molecules usually have much lower surface tension than polar ones.
Which of the following molecules is polar (please explain WHY) --- SF2. --- Br2. --- CCl4. --- BCl3. --- SO3.
Arrange the following molecules from least polar to most polar, explain your reasoning (6 points) 2. a. CH, b. CF.CI, c. CF.H, e. CCl,H
Based on what you know about intermolecular forces, which one of the molecules would require the most energy to break the IMF’s? How would you rank them in term of their boiling point? (phase changes, i.e. gas to liquid, solid to liquid, solid to gas, typically require energy to break the IMFs that holds the molecules together ). i. H2O ii. H2Te iii. HCl iv. HI
Why does sulphur (S8) have a high boiling point?
Because water molecules can form a variety of hydrogen bonds
with each other, water molecules tend to have more configurations
when they are by themselves than when they are mixed with other
molecules that cannot form hydrogen bonds. Imagine that the
interactions between water molecules and the molecules of a non
polar substance A (W-A interactions) are stronger than the W-W and
A-A interactions. In this case one can predict that:

Why do children tend to have high-pitched voices, and why do males typically have lower voices than females do?
1st attempt M See Periodic Table Two liquids - one polar, one nonpolar - have the same molar mass. Which one has the higher boiling point? Choose one: A. The polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions. B. They will have similar boiling points, since the dispersion forces depend upon molar mass. C. The nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together. D. The nonpolar...
