Which of the following compounds is most consistent with the IR spectrum given

below? Briefly explain.

The IR spectra for $C_6{H}_{12}O$ and $C_6{H}_{14}O$ are given below. Evidence from other

experiments indicates that the substituent is on the second carbon. Calculate the degree of

unsaturation for each compound. Also, decide which compound corresponds to each

spectra, and propose a structure for each compound.
