Resonance structures are required throughout organic chemistry. You’ll learn how to draw resonance early in orgo 1, and be tested on resonance intermediates in advanced orgo 2 mechanisms.

To help you take away the guesswork I’ve put together a brand new series taking you through the basics, starting with the question: **What IS Resonance, **all the way to rules, tips, tricks, practice, and even radical resonance.

I’m in the process of creating a short resonance guide to help you along. Download the Resonance Structures Guide free **coming soon.**

## Video 1 – What is Resonance?

The first step to mastery is understanding. Don’t just memorize ‘these arrows move here’. Instead, make sure you **get** why molecules resonate to delocalize their electrons, and understand the difference between ‘resonance hybrid’ and ‘resonance intermediates’. This and more is covered in Video 1 of this mini series.

## Formal Charge in Resonance

**When drawing resonance structures you’ll have to keep an eye on the change in formal charge. But you won’t have time to go through the lengthy/complex equation in your book. Instead be sure to utilize my Formal Charge Formula Shortcut.**

## Video 2 – Key Arrow Patterns in Resonance Structures

Now that you have a resonance foundation, it’s time to put your curved arrows to work.

They key to finding resonance structures, is knowing which electrons to move, WHERE to move them, and WHAT NOT TO DO!

## Video 3 – Major and Minor Resonance Structures

Not all resonance structures are created equally.

While an arrow CAN move onto a given atom, doesn’t mean it WANTS to. Once you’ve come up with all possible resonance forms, you’ll have to understand the stability of each structure to determine which are major and which are minor.

## Video 4 – Radical Resonance

When you think of resonance, you’re likely thinking of 2 electrons as a lone pair or pi bond. But radicals, or unpaired single electrons can also participate in resonance to increase their stability.

Video 4 shows you how to draw the ‘fishhook’ resonance for allylic and benzylic radical structures

## Video 5 – Resonance Structures of Benzene

Benzene is a unique molecule when it comes to resonance structures.

Learn how to draw its resonance, as well as resonance intermediates for substituted aromatic compounds including Electron Donating Groups which resonate into the ring and Electron Withdrawing Groups which cause resonance out of the ring.
