    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.

    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?

    a) Pyridine is used as (polar) solvent in this experiment.
    b) it also acts as a base to remove proton from cholesterol.

    2. Yes, the spherical molecules especially the chiral ...
