Identify at least two diagnostic absorptions in the IR spectrum of trans-cinnamic acid that are characteristic to the reactant and are NOT observed in the IR spectrum of the dibrominated product. 1) C=C stretch, observed near 1650cm-1 OH 2) C=C-H strech, observed near 3100 cm-1 Now, identify at least two diagnostic absorptions in the IR spectrum of 2,3-dibromo-4-phenylpropanoic acid (aka "the product" of this experiment) that are characteristic to the reactant and are NOT observed in the IR spectrum of the reactant. Br OH Br Absorption due to the C=C double bond in trans-cinnamic acid Absorption due to the C=O double bond in 2,3-dibromo-4-phenylpropanoic acid Based on the recorded IR spectrum, comment on the purity of the recrystallized product you obtained in the experiment.
