Chapter 1: Structure Determines Properties Acids and Bases Your organic teachers are quite likely to ask you questions like identify the most acidic protons or the most basic site in a molecule. These facts can be important for determining where a molecule is likely to react when treated with a base or acid respectively. Many students can not do this efficiently. The following topics are covered here: Definitions : Arrenhius, Bronsted, Lewis Acidity : K a and pK a Common acids in organic chemistry Basicity Common bases in organic chemistry Remember that acidity and basicity are the based on the same chemical reaction (but looking at it from opposite sides) and both happen simultaneously. In the following simple example the base, B , removes a proton from the acid, H- A : QUESTION : Can you think of another type of reaction that involves opposites simultaneously ? ANSWER Definitions There are three theories used to describe acids and bases : Acids Bases Arrenhius Ionise to give H + in H 2 O Ionise to give HO - in H 2 O Bronsted-Lowry A proton donor A proton acceptor Lewis An electron pair acceptor
