Question

 

1. Review either the IR spectrum of 1-butanol here Download 1-butanol hereor the same one which was provided in your lab manual.  Find and label significant peaks in both the furnished IR spectra of 1-butanol and also the IR spectrum which you obtained during your lab period.  

Below: report the wave numbers of prominent peaks; which spectrum the peak came from; and what does the peak signify.

For example: 1725 wavenumbers - Cyclohexanone - Carbon double-bonded to an oxygen.

2. How many compounds were present in the product mixture?  What is the most likely identity of the compounds?

3. Give the order of elution (from GC) for the compounds listed above (largest to smallest retention times
