Detailed breakdown of everything you need to understand when learning substitution and elimination reactions. I recommend starting with the intro and then learning the foundation topics including alkyl chain analysis, nucleophile v base, solvents and leaving groups. Once solid with the concepts start learning and practicing the reactions. I recommend pausing the video when a question is drawn out, attempting the solution, then watching for anything you may have missed. Enjoy!
