Textbook Question
Chapter 1.15, Problem 40P
Caffeine is a natural insecticide found in the seeds and leaves of certain plants, where it kills insects that feed on the plant. Caffeine is extracted for human consumption from beans of the coffee plant, from Kola nuts, and from the leaves of tea plants. Because it stimulates the central nervous system, it temporarily prevents drowsiness. Add caffeine’s missing lone pairs to its structure.

Glue adhesion usually requires a dry surface, so studying the chemistry behind the attachment of mussels to wet rocks can lead to
the development of new adhesive materials. Chemists used the compound shown to model the mussel foot proteins involved in the
adhesion process (Science 2015, 349, 628-632). Some of the nitrogen atoms in this structure are believed to play a critical role in
achieving the strong binding.

For this reason, chemists are frequently concerned with the 3D shape of their molecules and their bond angles. The oxygen atom shown in the structure has a tetrahedral electronic geometry, meaning we would predict that it would have 109.5° bond angles. However, the actual structure, the bond angles are smaller than 109.5°. Explain why this compression occurs. Make sure to discuss what’s happening around/what groups are present around the oxygen atom.arrow_forward4.
