Hints for identifying compounds in multiple-choice problems (problems 1:5); 1. Closely compare the given compounds. Determine which piece of information (molecular weight from MS, number of peaks in the NMR, presence of a special functional group in the IR, etc) would be the easiest for distinguishing between the given compounds. You might not need to use all types of given spectra to find your correct compound! 2. Based on your answer from step 1, consult the appropriate spectrum first. For...

Compound A: C6H14O
I've gathered that the Unsaturation Number is 0, so there is no
double bond or ring present. (I've also attached the IR and NMR
spectra on the bottom.)
But I'm having a hard time answering the following
questions.
Based on the molecular formula and the UN/DBE you calculated, check all the functional groups that could be present in compound A? Earlier, using the molecular formula and the UN/DBE, you came up with a list of functional groups...

NMR Help please!
Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...
