For the following problems, write a structure consistent with the molecular formula and 1HNMR spectrum. Also show the peak assignments, if there is more than one peak. Indicate the key information you used to deduce the structure. When you write down structures and you then realize are not correct, just put a line through them-do not erase or make them illegible, as we want to see your work, your thinking through each problem. 1. C5H12 The position of the single peak and the lack of coupling makes this problem easy. If it doesn't come to you, just write down the isomers of pentane until you see it
