NMR qiuestion

In a high resolution proton nmr spectrum of ethanoic acid, ch3cooh, the peak due to the hydrogen atoms in the methyl would be a singlet, why is this?

thanks :smile:

It's because there are no hydrogens attached directly to the adjacent carbon.

Because the CH3 group doesn't have any hydrogens on other carbons that are close enough to cause splitting, and all 3 hydrogens on the methyl group are identical.
