How many different hydrogen environments are there for pro-2-nol and which how many splits would each peak have and why does it split that way(what are its neighbours?)

I thought that the OH peak was not invovled in splitting?

The peak caused by OH is always a singlet, because of the oxygen's shielding effect.

As one of our Chemistry teachers said:

"So the O only lets the H have one peak because of electronegativity, basically it cockblocks it from seeing the other hydrogens"
