how can the ionic equation of the neutralisation of NaOH and HCl be written as either:

H+ + OH- >>> H20
or
H30+ + oh- >>> 2H20??

You'd get marks for either. But in reality, H+ ions cannot exist on their own. They always come in the form of H3O+.

I think it's something to do with Hydrogen's low electronegativity, but I'm not 100% sure.

I think it's because of the strong hydrogen bond plus the fact H+ is a cation?

What are you referring to? Why they only exist as hydronium ions, and not H+?

Well, my explanation of WHY it has a strong hydrogen bonding (might not be correct, but sounds logical to me) is that since hydrogen ions have the lowest electronegativity (it is only a single proton), then it will form strong hydrogen bondings with the Oxygen atoms of water molecules.
