Explain the term polarizability. What type of molecules tends to have high polarizabilities? What is the connection between polarizability and intermolecular forces?

Consider 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.

Which of the following compounds would be expected to form intermolecular hydrogen bonds in the liquid state? (a) H2Se (b) HCO2H (formic acid) (c) HI (d) acetone, (CH3)2CO

Identify the kinds of forces that are most important in holding the particles together in a crystalline solid sample of each of the following substances. (a) Kr (b) HF (c) K2O (d) CO2 (e) Zn (f) NH3

What is the relationship between strength of intermolecular forces and capillarity

In terms of the molecules intermolecular forced explain why the differences in boiling point exist? Identify ALL intermolecular forces present for each molecule

Polarizability is defined as the extent to which the electron cloud surrounding an atom or molecule can be distorted by an external charge. Rank the halogens (F2, Cl2, Br2, I2) and the noble gases (He, Ne, Ar, Kr, Xe) in order of polarizability (from least polarizable to most polarizable). What characteristics of these substances could be used to determine this ranked order?

Place the following three choices in order of increasing intermolecular forces.C 5H 12C 4H 10C 3H 8

Answer the following questions dealing with intermolecular forces and the physical properties that depend upon them. 1. List all of the IMFs present in a pure sample of the following chemicals: H₂O CH4 HCN CH,F CO₂ CH3NH2
