Lewis Acids

[Ariel Fern 2B]

Lewis Acids are electron acceptors, but what is the best way to determine that from a Lewis Structure? I'm having a little trouble visualizing the concept of Lewis Acids in terms of where an electron pair can be added on an atom. For Lewis Bases, I can see where lone pairs could be donated, but I'm just struggling on visualizing the same thing for Lewis Acids accepting electron pairs.

Boron and other atoms in its group can act as Lewis acids because they cannot obtain a full octet by themselves, having only 3 valence electrons. Positively charged atoms can also act as Lewis acids since accepting a lone pair will neutralize the positive charge.

Lewis acids are molecules that are often positively charged that would bond to an atom with a lone pair such as H+.

Hi,

I found the diagram on this website helpful!

You can see that the lewis acid is H+ which is accepting the electron from oxygen.
