Flow of Electron Density Curved Arrow Notation

2 Flow of Electron Density Curved-Arrow Notation 

If necessary, review the suggested sections to prepare for this chapter. 

This chapter will focus primarily on Bronsted-Lowry acids and bases. There is also a brief section dealing with Lewis acids and bases, a topic that is revisited in Chapter 6 and subsequent chapters. 

The definition of Bronsted-Lowry acids and bases is based on the transfer of a proton (H ). An acid is defined as a proton donor, while a base is defined as a proton acceptor. As an example, consider the following acid-base reaction  

In the reaction above, HCl functions as an acid because it donates a proton to H2O, while H2O functions as a base because it accepts the proton from HCl. The products of a proton transfer reaction are called the conjugate acid and the conjugate base
