Consider the structure of caffeine (re-draw it here), and answer the following questions from a structural perspective.
- Caffeine is an alkaloid and, as such, is weakly basic. Circle and label the basic atom or atoms (hints: consider the base in Experiment 4C, and consult the Derivative procedure on page 235).
- Identify (circle on your structure) and discuss two different structural features that would account for solubility in methylene chloride (hint: think intermolecular forces).
- Identify (circle on your structure) and discuss two different structural features that would account for solubility in water (hint: think intermolecular forces).
