Ive been performing poorly all semester with my old school Orgo professor. I even contemplated dropping the course because it was seemingly a different language to me. Then I found out about your videos and purchased a subscription on your website. Thanks to you, the content became so much more understandable and my grades improved immediately. This is definitely a course that made me question if I still wanted to apply to Dental school. After studying your videos, I am right back on track with my ultimate goals. You do a phenomenal job helping us understand and enjoy organic chemistry. Thank you so much man you are literally a life and GPA saver.

I don't think there is any other youtube channel that teaches ochem concepts relevant to classes that college students take like you do. There's ochem tutor, but he lacks the organization and logical progression (just random videos scattered all over). I appreciate him, but I cannot find value in it like I find in your videos.

I can't say how much I appreciate you right at this moment. I have a ochem exam tomorrow and this stuff always confused me. The deal is if I get an A in the exam, I'll be getting a C as a grade. With this video, for sure I am going to be getting an A. I appreciate you and your videos!

Hi Chad! How come at 7:51, you don't worry about the Br being antiperiplanar to the Hydrogen because its a E2? And doesn't 2(degree symbol) have priority over 1(degree symbol) in E2?

at 6:10, since there is an applied heat in the reaction, doesn't that mean it would prefer proceeding with the elimination reaction only?

In your first example, you just said it would be sn1/e1 but what if I need to choose which reaction it would be? How would I go about finding out which one that is?
@ChadsPrep4 жыл бұрын
SN1 and E1 are difficult to distinguish from one another and under most conditions you get a significant amount of both occurring. However, some textbooks and professors will emphasize that E1 will be favored at higher temperatures. If your professor has made a point of this go with it. Hope this helps!
@cyrilbinoyskariah31093 жыл бұрын
sir but what about for polar protic , aprotic and non polar solvents, in that case how to choose sn1, sn2 , e1,e2????????
@ChadsPrep3 жыл бұрын
In theory the solvent will have less importance in determining which mechanism or mechanisms are likely, but in practice if you're performing these reactions in the lab then you should definitely pay attention to your solvent. I do discuss the role of the solvents in the earlier lessons in this section: how SN1 and E1 reactions must have a polar protic solvent, and how E2 reactions are faster in polar aprotic solvents but work just fine in polar protic solvents too. It is the SN2 reactions where we often oversimplify the picture because reality is more complex than we want to explain to students. Most SN2 reactions strongly prefer polar aprotic solvents. Many textbooks and professors will say nothing more on the topic, but some will go further getting closer to the truth. I stopped here in the lesson as that is what will be required of the majority of students. But the truth is that smaller nucleophiles (from period 2 on the periodic table) that are negatively charged (most strong nucleophiles are) typically require the solvent to be polar aprotic. But larger nucleophiles (period 3 and below) will typically still react faster in polar aprotic solvents but tend to work just fine in polar protic solvents too. And the last level of complexity is that neutral nucleophiles (there aren't too many strong nucleophiles that aren't negatively charged) actually react faster in polar protic solvents, but I've only seen one textbook that even presents this. So now you've got something closer to the truth and perhaps your professor is requiring more out of you here than the average student than you're asking about it. But 90% of the time you can probably determine the mechanism by an examination of the just nucleophile and substrate. But if you do look at the solvent you could make the following generalizations: Polar aprotic solvent --> SN1 and E1 are not possible so the mechanism will be SN2 and/or E2 Polar protic solvent --> More likely to be SN1 and E1, but that doesn't have to be the case as most E2 reactions work just fine in polar protic solvents and some SN2 reactions work in polar protic solvents as well. And I didn't mention it but you are not likely to see nonpolar solvents entering the discussion as they are not appropriate for substitution and elimination reactions. They don't form ion-dipole interactions which means they can't stabilize carbocations so no SN1/E1 and the majority of strong bases and nucleophiles, being ionic, won't be soluble in nonpolar solvents so no SN2/E2. Hope this helps and happy studying!
