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...
