Question

1. STRUCTURE OF UNKNOWN (Draw Below) Code Numbs 2. PROTON MAGNETIC RESONANCE SPECIRALDATA Complete the table below by listing the chemical shifts of all of the signal patters in the num spectrum of your compound (chemical shifts of clear multiplets are single numbers at the midpoint of the patter chemical shifts of complex multiplets are given as mango) Assign the multiplicity (singlet, double triplet. quartet, etc., complex multiple as appropriate). Give the integration values (whole number tatio from integration trace on your spectrum). Finally give your assignment for each signal do this by designating each signal pattern by letters, A, B, C, etc., and using these letters to label the different sets of protons in the structure you have drown in part 1, above. CHEMICAL SHIFT (5) in ppm) MULTIPLICITY NTEGRATION (Whole + Ratio) ASSIGNMENT 3. INFRARED SPECTRAL DATA Fill in the table below using data from the infrared spectrum you ran List the specific frequencies for those characteristic absorptions which can be assigned for your compound round values off to nearest whole wave number). Considering the transmittance values of the peaks reported, assign their appearance a strong. weak sharp, broad, ate, as appropriate. In the third column fisit the specific vibrational assignment made for each absorption reported (le, sp C-H streich; C.O stretch: Aryl C-Hout-ol plane bend for o-disubstituted becene; etc.) FREQUENCY () APPEARANCE ASSIGNMENT
