2. (10 marks) The four organic compounds shown below as A, B, C, and D share the same molecular formula, C6H10O2. Their IR spectra are given as data set #1, \#2, \#3 and \#4. Match each of the four spectral data sets ( #1,#2,#3,#4 ) to the correct compound (from one of A, B, C or D). Explain the spectral features that you have used in this process (aka spectral assignment). Hint: Focus your attention on the peaks that would allow you to differentiate between the four different compounds, rather than spectral features that they have in common. A B C.
