34. Hot and spicy foods contain molecules that stimulate pain-detecting nerve endings. Two such molecules are piperine and capsaicin: H H - CH=CH_CH=CH- H. H. H. Piperine H,CO, „CH2. CH2 NI (CH,), / CH CH CH, HO `H H `CH, Capsaicin Piperine is the active compound in white and black pepper, and capsaicin is the active compound in chili peppers. The ring struc- tures 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 show- ing all lone pairs of electrons. h. How many carbon atoms are sp, sp², and sp'hybridized in each molecule? c. Which hybrid orbitals are used by the nitrogen atoms in each molecule?
