Recently in Chemistry we have been doing about how it is possible to identify carbon compounds by how many proton environments there are around a molecule. For this we look at graphs with various peaks dotted around them, this is not what bothers me, what bothers me is that some of these peaks have been split into a number of peaks. We have been taught about the n+1 rule. Consider ethanol: Code (Text): H H | | H - C - C - O | | \ H H H There would be 3 proton environments around that molecule, one on the methyl group on the left, one for the two protons on the right hand carbon molecule and another for the proton bonded to the oxygen. The methyl group peak would be split into three separate peaks, the two protons on the right hand carbon peak would be split in to four separate peaks and the proton on the oxygen would just be a single peak. I am realy looking for as simple an explanation as possible as to why peaks split at all. Is that possible?
