Need help as soon as possible, my assignment is timed but I don't know how to complete this. This is all I was given in the question, nothing more was provided. --First, using the molecular formula of C7H10BrFS please draw a bond-line structure and the corresponding 1H NMR spectrum. Second, using the same molecular formula, please draw a constitutional isomer and the corresponding 13C NMR. Please be sure to have both representations properly drawn as well as the corresponding spectra.

3. In lecture, we gave a recursive algorithm for the Tower of Hanoi problem which uses Hn many moves to solve the puzzle, where H1 = 1 and Hn+1 = 2Hn +1. One might object that Hn is not an accurate measure of the amount of effort needed to carry out said algorithm; after all, moving a large disk takes more work than moving a small disk!...
