- Explain the data related to odour in terms of types of bonds. Do you think that a substance can be relatively volatile and not have an odour? Give an example.
- Explain in terms of bonding the variations in melting between the two solids.
- Are the relative strengths of covalent and ionic bonds comparable, when melting points are compared? Explain.
- At what temperatures do KBr and p- dichlorobenzene melt?
- In p-dichlorobenze, are the intermolecular or intramolecular forces greatest? Explain your answer.
- Use the periodic table or chart of electronegativities to predict whether or not the following substances are largely ionic or largely covalent: LiF, ICl, Na2O, SO2, and BaI2.
LiF
ICl
Na2O
SO2
BaI2
- Give one use for each substance.
