Vixen Joyful mono Molecular H7 ~ 21 ~ 21 11483-2

in this online lecture we're going to talk about protons bonded to oxygen and nitrogen how they appear on the h and mr what we're going to see here key point number one is that no splitting is observed for protons on a nitrogen or an oxygen if the sample is run with trace amounts of acid or base this is due to of something called proton exchange we're also going to see number two that the signals for protons on an N or O are usually broader than other signals on the h NMR this is to our benefit because it makes these signals easier to pick out on an H NMR so let's understand our key points here let's say you have this alcohol right here and you put him in the H and M R notice because it's an alcohol you have a hydrogen bonded to an oxygen but let's say we run our sample pure and dry this means the sample molecule is simply by itself in the NMR there's no solvent and no other reagents le
