Consider the following molecule and its 1H NMR spectrum. Both its cis and trans isomers are shown. Parts of the spectrum have been cropped out. CI CI 1H 1H 1H 3H PPM A. Assign the peaks in the 1H NMR spectrum. He has already been assigned for you. The methyl hydrogens may be labeled Hd. You should be able to label the peaks without knowing which geometric isomer the molecule is. B. Calculate Jab and Jac. Recall that splitting is reciprocal so the splitting of Ha to Ho is the same as the splitting of Hb to Ha. Assume the carrier frequency is 300 MHz. Show all work. 6.55 6.49 6.14 6.12 с 06 4.88 4.84 4.82
C. Which geometric isomer generated this spectrum? Briefly explain your answer.
