Implications and Applications
Activity 1 was adapted from Experiment B22 in the following source:
- Explain the odor data in terms of bond types. Do you think that a substance can be relatively volatile and not have an odor? Give an example. How could the sensitivity of one's nose affect the observations made?
- Explain differences in melting points in terms of types of bonding in the four substances.
- Does a comparison of melting points give any information about the relative strengths of ionic and covalent bonds? Explain.
- Are intermolecular or intramolecular forces greater for lauric acid? Explain your answer.
- How can the results of the solubility tests be explained? What is the major difference in the nature of water and cyclohexane as solvents?
- Explain the classification of the unknown as ionic solid, covalent molecular solid, covalent network solid, or metal.
