This is may be your 1 million and 1 “thank you”comment, the protic solvent undo the ability of Nu- is the one sentence make my day my lecturer did not know explain this way, this is crystal clear now. Thanks a lot
Thank you so much for taking the time to share this. This is why I love these live sessions, I wouldn't even have thought to explain it until it was asked by a student during the session. I was never taught this in undergrad and found it very confusion until I finally found the explanation (don't even recall where) Everyone is so focused on the WHAT. I challenge you to ask WHY!! Best of luck on your exams
@@Leah4sci thank you very much and hope u getting better soon.!!!!
Leah without u idk where I would be rn in ochem. Ur a miracle worker, my final is this saturday (and i have a physics final right after) 12-3, 3-6pm. Im getting B's but without your content I'd be getting C's or worse. Thank you
Oh wow, I can't imagine taking orgo and physics back to back without a mental break in between. So happy to hear that my videos are helping and I wish you the absolute best this Saturday
You are incredible! I've always hated Organic Chemistry, this semester I'm taking "Organic II" and my teacher makes the subject much more complicated than it already is.She looked me in the face and told me not to even try when I didn't understand a question on the test, that "when you don't know, you don't know." She said she doesn't understand why some people take Chemistry in college, that many can't realize that it's not for them. I've lost count of how many bad thoughts she made me have, how many nights I thought about giving up, or how many times I cried in my bed. But in the midst of all the chaos I had your classes on RUclips, classes on the subject I hate the most, but the teacher I love the most! Thank you for making Organic Chemistry "less worse", I hope one day to love it as you seem to. Thank you for being an incredible teacher and democratizing access to your classes. I'm sure you've saved many students like me.
Love u Leah, kisses from Brazil♥️
Oh wow, your professor sounds like someone who absolutely has no business teaching. a teacher should TEACH and inspire, strive to make the complicated learnable, not crush a student's spirit. I'm honored that my videos are able to fill in where your professor is clearly lacking
@28:30 it could be also a SNi rxn type using SOCl2 and Pyridine in cyclohexane , or am i missing something ?
So helpful thanks
Glad it was helpful!
Do aprotic solvents shut down E2?
I feel like for 2-iodobutane with sodium hydroxide in acetone would be an E2/Sn2 major
Aprotic solvents don't let bases act like bases because the solvent doesn't provide the partial positive H for it to go after. For this reason the molecule is more likely to act as a nucleophile UNLESS it's specifically a poor nucleophile but strong base. What you described would be an SN2 reaction
Thank you! sosososo helpful
You're very welcome! I hope you ace these questions on your final
At 56:14 which one is major product mam?
Either substitution or elimination production
SN1 and E1 are often in competition and so while one may be slightly greater than the other, professors expect you to show both products. When heat is added you get more elimimation
You are awesome
Thank you so much! You are also awesome
Pls teacher, can I make a request? I hv exam on 19th and I don't understand sm topic that my Lecturerer taught and it seems reluctant in responding my question. pls if you can just give me brief lesson on them? or even re-direct me if u've made video on them already.Thank u.
Which specific topic are you asking about? I have hundreds of videos here on my RUclips channel and a more organized and detailed video library in my Study Hall membership here: leah4sci.com/join
hi mam when you go live can you send the time table
