Chapter 9, Problem 38E
Hot and spicy foods contain molecules that stimulate paindetecting nerve endings. Two such molecules are piperine and capsaicin:
Piperine
Capsaicin
Piperine is the active compound in white and black pepper, and capsaicin is the active compound in chili peppers. The ring structures in piperine and capsaicin are shorthand notation. Each point where lines meet represents a carbon atom.
a. Complete the Lewis structure for piperine and capsaicin, showing all lone pairs of electrons.
b. How many carbon atoms ate sp, sp2, and sp3 hybridized in each molecule?
c. Which hybrid orbitals are used by the nitrogen atoms in each molecule?
d. Give approximate values for the bond angles marked a through l in the above structures.
