3. Compare the following set of molecules in terms of the properties indicated in
each item. Explain your answer based on their intermolecular interaction not
on actual values from books or other sources.
a. Butane and butanol in terms of boiling point
b. Cl2 and HCl in terms of solubility in water
c. Propane and Hexane in terms of physical state
1. Discuss the three main intermolecular forces described in chapter 11 using relevant examples.
2. List the following substances: Ar, Cl2, CH4 and CH3COOH in order of their increasing strength of intermolecular attractions. Give reason for your answer.
3a. Which intermolecular force is present in Water? Explain the reason for your answer.
b. Some of the remarkable consequences of the intermolecular force present in water can be used to explain the "Expansion of water upon freezing", which explains why icebergs float in water and why water pipes burst in freezing temperatures. Question: Using the concept of the intermolecular force present in water: Discuss why water expands upon freezing.
4."CH3OH boils at 65*C, while CH3SH boils at 6*C" . Which intermolecular force accounts for this difference? Explain.
