INSTRUCTIONS: Complete "IR Practice I" packet by matching each IR spectrum with the structure (from the options below) that best fits it. Look for both the presence and absence of certain bond signals in the IR spectrums to provide evidence for your selection. (If you would like more practice to do on your own, complete the "IR Practice Il" packet.)
