1) Identify the carbonyl stretches in the IR spectrum for both ethyl cinnamate and your product. Based on your understanding of IR spectroscopy, which carbonyl bond is stronger? Explain why. 2) Starting from the resonance structures on the right side below. Draw two additional resonance structures for ethyl cinnamate and one additional resonance structure for your product. Do not involve the aromatic ring in resonance. 3) Explain how the resonance structures you drew in #2 above justify the bond strength observation in #1.
