Just a note - in this video I do not make a distinction between SN2 and E2 as which is major or minor. You may need to follow a guideline in your own classes, such as when you have a secondary or tertiary leaving group, E2 is favored (major), while with primary leaving groups, SN2 is favored. This is due to not only steric hindrance as an issue for secondary/tertiary leaving groups but also the additional stability of the more substituted alkenes formed in E2. Leave comments if you have questions about that. Good luck!
