Question

2. Considering that one degree of unsaturation is one pi bond or one ring, how many degrees of unsaturation does curcumin have? How many degrees of unsaturation does tetrahydrocurcumin have? 3. What is the source of hydrogen in the hydrogenation of curcumin? How many moles of H are produced per mole of the source? Why are we using excess? 4. What absorptions in the infrared spectrum of curcumin do you expect to disappear if the alkenes are completely hydrogenated? What absorptions do you expect will stay in a similar region?
