The OH signal is all the way to the right when it's very concentrated with alcohol. The spectrum you showed is for 10% alcohol and 90% solvent. The more diluted, the more the OH signal shifts upfield to the left.

so we are sending radiowaves to a solution bec we cannot do it in a single molecule.. thanks for clarifying

Is it possible SDBS could be incorrect? Literally every other H-NMR spectrum I look up for ethanol has the O-H hydrogen at just under 5 ppm.
@spotsies6 жыл бұрын
Note that the distance the peaks appear varies based on the strength of the applied magnetic field, that's my guess why. Using a magnetic field of about 500MHz, the hidroxyl H appears between 5.5 and 5.0 ppm, as opposed the spectrum showed by him was made using abour 89.56MHz.
@devinlewis51166 жыл бұрын
I asked my O Chem professor and he said that both spectra are correct, it is actually the difference between the solvents used. Deuterated chloroform will give the spectrum that SDBS provides, and d-6 DMSO gives the O-H hydrogen around 5 ppm.

Please the H on the O shows splitting with the adjacent H so I'm confused 😕 . It shows a triplet

In general, why is H bonded to O so downfield?
@GoodFeelingsOnly5 жыл бұрын
Oxygen is a very electronegative atom, so it causes a deshielding effect on the H bonded to it (meaning it pulls all the electrons closer to him).
