Discussion: I determined the structure of the product by making predictions about what I already knew. Pd/C uses molecular hydrogen to dydrogenate double bonds. Throught he reading, I figured that the carvone would become an enol and then be dehydrogenated on its ring as it would create a benzene ring, a very stable molecule. The hydrogens that
