Unknown Spectroscopy Practice Problems: Problem #9 What hydrocarbon (hydrogen and carbon only) formula would you use to start this problem? How many degrees of unsaturation does it have? How would you revise your molecular formula and degrees of unsaturation based on the IR spectrum? What are possible source(s) of that amount of degrees of unsaturation?
