Explanation/Answer cannot be hand-drawn! Must be typed or illustrated digitally Analyze IR data: Identify peaks in the IR spectrum and identify their corresponding functional groups within the sample molecule. The molecules identity is given with the IR data. Analyze H NMR: Identify which hydrogens the peaks resemble. Identify their location in the molecule along with their shift, splitting, and integral. The molecules identity is given with the H NMR.
