This is an IR spectrum of a sample of methyl cinnamate. In what way do you expect the IR of the product (methyl cinnamate) to be different than the methanol and cinnamic acid that was started with? Based of the IR shown, Is there ar OH stretch? Is there a C=0 stretch? Where should the C=O stretch for this ester (methyl cinnamate) appear?<\/p>\n\n\n\n
