Hello, I did an experiment in which I added 500 mg of cholesterol to 1.5 mL of dry pyridine. Then I added 1.7 mmol of benzoyl chloride and heated the mixture.

Questions:
1. Explain two reasons why pyridine was used in this experiment.
2. Do spherical molecules exhibit liquid crystalline behavior?
3. Could either a primary or a secondary amine be used in this experiment in place of pyridine? Why of why not?
