  • This is it! This is what you've been freaking out about in class! How the hell do you choose the mechanism that's gonna happen? Is it SN2, SN1, E2, or E1? Woe is you, what will you do. Why not listen to Professor Dave? He's got the hottest chemistry tips in town. That cute boy or girl in class will be so impressed when you apply what you've learned here and have all the answers at the next lecture. Don't worry, I won't tell. But you should, I need the promo.

    How can 18 minutes of explanation be more helpful and clear than one entire semester of my teacher explanation?
    Thanks for this lesson Dave.

      I totally agree with this. Summer tuition for Organic is over $900, when I can sit on CZcams and learn it for free from someone who actually uses teaching methods. By far my favorite Organic Chemistry tutors. Keep up the fabulous work

    very simple explanations of how to narrow it down thinking like a student! Thanks professor dave, the cute girl in my class will be so impressed!.
    P.S. good way to remember which temperature favors the substitutions or eliminations....if it is a low temperature and you are cold you would want to SUBSTITUTE your wardrobe for something better...if it is too hot and you will want to ELIMINATE clothing to cool off.
