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

Concept #1: What you need to know about types of chemical reactions.

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.

Concept #2: Recognizing Acid-Base Reactions. 

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)  

Concept #3: Recognizing Substitution Reactions. 

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

Concept #4: Recognizing Elimination Reactions. 

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

Concept #5: Recognizing Addition Reactions. 

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.
