OH by itself is not a complete compound. It is a hydroxyl group, which is a functional group commonly found in organic chemistry.

The name of the compound depends on what the hydroxyl group is attached to. For example:

* H-OH is water (H₂O)

* CH₃-OH is methanol (a type of alcohol)

* C₂H₅-OH is ethanol (another type of alcohol)

So, you need to provide more context to determine the name of the compound containing the OH group.
