Important information about Pre lab questions
1. Why is sulfuric acid, rather than hydrochloric acid, used to catalyze the dehydration of alcohols?
2. A sample of 150 mg of an organic compound is dissolved in 7.5 ml of water. The solution is paced in a 20-cm polarimeter tube and the rotation measured in a polarimeter. The rotation observed was +2.676 degrees. Distilled water, in the same tube, gave a reading of +0.016 degrees.
Calculate the specific rotation of the compound.
3. Which of the following compounds have a meso form?
2,3- Dibromopentane
2,4-Dibromopentane
2,3-Dibromobutane
Why is it a meso form?
4. Compounds such naphthalene and 1,4-dichlorobenzene fine use as mothballs since they sublime at a slow rate at atmospheric pressure. Explain this behavior in terms of the structure of the molecules.
