Issue with Ester Hydrolysis 1H NMR results

In the synthesis of propionic acid from methyl propionate, the product 1H NMR has a signal of about 7.8 ppm. I don’t think that is typical for a carboxylic H. Even SDBS lists that signal at close to 12 ppm.

@michguti – I agree with you. It appears to be incorrect. Thank you for pointing that out to us, we will correct it.
