Benzene is a unique molecule when it comes to resonance structures. This video will show you how to draw the ‘circle’ of resonance for benzene, as well as resonance intermediates for substituted aromatic compounds including Electron Donating Groups EDG which resonate into the ring and Electron Withdrawing Groups EWG which cause resonance out of the ring. […]
Orgo Basics Video Series: Video 6 Resonance structures are alternative Lewis structures for a molecule or an ion. To draw the resonance hybrid or structures, we are moving electrons between adjacent atoms. Overwhelmed? In the video below, you will see an explanation and illustration of resonance structures and resonance hybrids step-by-step. This will help you visualize […]
Orgo Basics Video Series: Video 7 You know now how to draw the resonance structures. But which one is the most accurate resonance structure? Which one is most representative of the molecule? In this video, I will explain what it means to be the most stable & least stable resonance structures and how to identify it […]
Think you know Resonance structures? Test your knowledge with my Resonance Structures Practice Quiz! Practice is ESSENTIAL to mastering Organic Chemistry. You have to be able to apply the skills you are learning. First, complete the Resonance Structures Practice Quiz, and then watch this video where I go over the first three question solutions and explanations step-by-step! (Watch […]
Once you’ve mastered the rules for which electrons to resonate (video 2) it’s important to understand which resonance structures are considered important or major contributors, and which are considered less important or minor contributors. This video helps you rank resonance structures based on charge, electronegativity and more. (Watch on YouTube: Structures. Click cc on bottom right […]
Not sure if you’ve mastered resonance structures? Looking for extra practice? Resonance is a critical topic in your organic chemistry curriculum. After watching the Resonance Structures Video Series test your knowledge with this short quiz below. Give it a shot, then check the solutions (linked at the end) and see how you did. Resonance Structures Practice […]
Understanding resonance structures is the first step. Knowing which electrons CAN and CAN’T is key to figuring out how to draw additional resonance structures. This video shows you what to avoid when drawing resonance, followed by key arrow patterns to look out for in determining additional structures. (Watch on YouTube: Key Arrow. Click cc on bottom right […]
The first step to learning resonance structures in organic chemistry, is to comfortably know the answer to this question: What is Resonance? 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 […]
