Assignment:
Q1. Why is sulfuric acid, rather than hydrochloric acid, used to catalyze the dehydration of alcohols?
Q2. 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.
Q3. Which of the following compounds have a meso form?
2,3- Dibromopentane
2,4-Dibromopentane
2,3-Dibromobutane
Why is it a meso form?
Q4. 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.
Provide complete and step by step solution for the question and show calculations and use formulas.
