Lone Pairs in Bases?

Postby JasonNovik3A » Fri Nov 10, 2017 10:13 am

Do Lewis Structures with lone pairs usually means it’s a Lewis Bass? And if so, why?

Yes, an atom with a lone-pair of electrons can be a Lewis base because it donates its electron pair to a Lewis acid.

And likewise, a molecule that needs a lone pair to be stable would be a Lewis acid. You can think about OH- and H+ as examples. H+ is the acid because it needs another election to be stable while OH- is a base because it can donate an electron in order to be stable.
