Interpretation:
The parts are to be answered by considering the given compounds.
Concept Introduction:
The Lewis structure of a molecule is a representation of the molecule in which valance electron of an atom shown around as dots.
The polarity of the molecule depends upon the difference of electronegativity between the atom present in the molecule.
Hydrogen bonding occurs when the molecule has hydrogen atom directly bonded to either oxygen, fluorine or nitrogen atom.
Dipole-dipole forces occur when positive end of a polar molecule attracts the negative end of the other polar molecule.
Dispersion forces are weakest intermolecular forces. The electron of two neighbor atoms occupy the positions that make the atom form temporary dipoles.
The boiling point of the molecule depends upon the intermolecular forces and the molar mass of the compound.

- 8.39 Under what circumstances are ion-dipole forces important?arrow_forward8.41 What is the specific feature of N, O, and F that causes them to play a role in hydrogen bonding?arrow_forwardWhat are intermolecular forces? How do they differ from intramolecular forces? What are dipole-dipole forces? How do typical dipole-dipole forces differ from hydrogen bonding interactions? In what ways are they similar? What are London dispersion forces? How do typical London dispersion forces differ from dipole-dipole forces? In what ways are they similar? Describe the relationship between molecular size and strength of London dispersion forces. Place the major types of intermolecular forces in order of increasing strength. Is there some overlap? That is, can the strongest London dispersion forces be greater than some dipole-dipole forces? Give an example of such an instance.arrow_forward
- 8.45 Describe how interactions between molecules affect the vapor pressure of a liquid.arrow_forward8.36 Why are dispersion forces attractive?arrow_forwardThe compounds ethanol (C2H5OH) and dimethyl ether (CH3OCH3) have the same molecular formula. Which is expected to have the higher surface tension? Why?arrow_forward
- Why do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.arrow_forwardConsider the iodine monochloride molecule, ICI. Because chlorine is more electronegative than iodine, this molecule is a dipole. How would you expect iodine monochloride molecules in the gaseous state to orient themselves with respect to each other as the sample is cooled and the molecules begin to aggregate? Sketch the orientation you would expect.arrow_forwardWhich of the following compounds would you expect to exhibit only London forces? a potassium chloride, KCl b c silicon tetrafluoride, SiF4 d phosphorus pentachloride, PCl5arrow_forward
- Silane SiH4, phosphine (PH3), and hydrogen sulfide (H2S) melt at 185 C, 133 C, and 85 C, respectively. What does this suggest about the polar character and intermolecular attractions of the three compounds?arrow_forward8.43 Identify the kinds of intermolecular forces (London dispersion, dipoledipole, or hydrogen bonding) that are the most important in each of the following substances. (a) methane (CH4) , (b) methanol (CH4OH) , (c) chloroform (CHCl3) , (d) benzene (C6H6) , (e) ammonia (NH3) , (f) sulfur dioxide (SO2)arrow_forwardReferring to Figure 9.7, state what phase(s) is (are) present at (a) 1 atm, 10C. (b) 3 mm Hg, 20C. (c) 1000 mm Hg, 75C.arrow_forward
