Overview of Reactions

Now you’re finally getting ready to start understanding types of chemical reactions. Oh joy! 

We’re gonna learn about 4 different types of chemical reactions. You don’t actually need to understand these! Just be able to recognize them for now.

In this reaction, two molecules of opposite charges react to exchange a proton. (There are some exceptions that don’t, but we’ll get to this later)  

This is an acid-base reaction where an atom (or group of atoms) other than protons are exchanged.

Here, two single bonds (σ) are removed to create one double bond (π).

In these reactions, one double bond generates two new single bonds.

  • Addition and Elimination are inverse reactions! In some cases they can perfectly cancel each other out.
