Acids And Bases
« on: November 14, 2014, 01:40:27 PM »
I understand that Arrhenius Acids and Bases are defined in terms of H+ and OH-. And Bronsted-Lowry Acids and Bases are defined in terms of Protons (donors and receiver). Whereas Lewis Acids and Bases are defined in terms of Electrons (donors and receiver).

Are these different conceptual indication of all the Acids and Bases. Or are there specifically Bronsted-Lowry Acid and another Lewis Acid? For instance my textbook quotes that Alcohols and Phenols are Bronsted Acids. Can I have a look into the basics of Acids and Bases?

Lewis bases are electron-pair donors.  Not all Lewis acids are Bronsted-Lowry acids.

In other words - each generalization goes a step further and allows explaining wider class of reactions as acid/base reactions. Every Arrhenius acid is a Bronsted-Lowry acid, and every Bronsted-Lowry acid is a Lewis acid. It doesn't always work the other way.
