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 that could be present in compound A. Now using the IR data you should be able to narrow this list down. Below, check all the functional groups that could be present in compound A. Examine the 1H spectrum of Compound A. Below is a table summarizing the spectral data. Using that data, assign each peak to the type of alkyl group. Propose a structure for Compound A. Once you have a structure, it is always helpful to go back throught the spectral data and make sure that the structure you came up is consistent with ALL of it.
