A major part of the DAT organic chemistry section is knowing your reactions. I have constructed the following reaction sheet to expose you to every reaction that could possibly show up on the DAT. You do not need to memorize every single reaction to score well on the organic chemistry section. However, you should be Read More

Ever wonder who the teacher is in our chemistry solution videos? That’s Dr. Mike Christiansen, our in-house chemistry expert. Dr. Christiansen has a PhD in organic chemistry and has been teaching students chemistry for nearly 12 years. I thought it would be important for you to learn more about him, so I asked him to Read More
Occasionally, on the DAT organic chemistry section, you’ll be asked about one of the chemical lab tests you likely used in your lab sections to identify the functional groups in a molecule. Below is a list of the most common lab tests, which functional group they test for, and what a positive result looks like. Read More
See our previous post on the 6 Important EAS reactions to know for the DAT. Now we need to focus on benzene substituents and how they affect the location of subsequent additions. Here’s a list of the ones you would most likely see: Electron donators / Activators (strongest to weakest): -O–, -NR2, -NH2, -OH, -OR, Read More
In an Electrophilic Aromatic Substitution (EAS) reaction, the benzene ring acts as a nucleophile that attacks an electrophile. The reaction mechanism below outlines the flow of electrons that occurs during all EAS reactions. Here are the six EAS line reactions you should know for the DAT:
