H NMR Splitting Question

[Monkeymaniac]

For the following alcohol, will the NMR signal for H of OH splitted
into triplet or singlet? I wasn't sure if two adjacent atoms that have
nonequivalent protons attached should be strictly carbon only to have the n+1 split rule appied or not. Thanks in advance!

From my understanding, it doesn't split because the hydrogen is protic. Instead what you would see is a broad peak from the 3-5 ppm region with no splitting.

Hmm, I see. I think that makese sense.
So we don't get splitting for a proton in hydroxy group for any molecules (alcohol, acid, etc.)?
But why would hydrogen bonding inhibit the magentic field generated
from nearby protons from affecting the -OH?
Can I please get some second opinions? Thank you.

Splitting comes from distinct constructive/destructive interference between the fields associated with the charged particles. My guess would be these distinct phases don't exist with the particle (proton) not locked into one place. It would be more of a broad range (and thus the wide weak)
