In this video, you’ll learn how to identify a leaving group and how to analyze its effects in SN1, SN2, E1 and E2 reactions. You’ll also learn to compare the relative sizes of leaving groups and see how that changes a group’s ability to hold the burden of negative charge. Additionally, you’ll see how resonance can affect a leaving group’s ability to hold charge and increase its stability in solution.

Thank you so much, ma'am Leah! I have an org chem exam coming up, and your videos are a big help!
You're welcome! Good luck on your exams.
I know it's been half a decade, but how'd your exam go?
I am very much dependent on your videos to get " A plus" in my two classes. I am hopeful that I will end up not only good marks but also good understanding of the concepts.
So happy to share and help you in your class!
your efforts are appreciable...may u become more popular nd successful. god bless u
Thanks you! :)
a small question ,why good leaving groups are weak bases . I have gone through your videos they were amazing thanku
Leah Fisch iodine is a good leaving group . but it also a better nucleophile. how? . ...I am confused
@@sunehrikiran5638 because iodine is 2nd most strongest after NH3 so if NH3 will attack than iodine will leave but it will be a good leaving group but if iodine attack on Br, Cl, F, which are less strong than it , Br,Cl, F will leave because iodine is more stronger than them and so Iodine will be a good neuclophile in this case.
@@sunehrikiran5638 but its been 3 years since you asked😅
@@KashafNaeem. thank you so much
@@A_katz1 no problem❤️
Thank you so much for your videos. I have been watching them sporadically before my exam tomorrow! I feel a lot more confident now. By the way I got an 86.5 on my first exam in Orgo, thanks to your help and my professor’s help as well.
Wow! That's awesome! Glad I could help :)
Leah4sci I ended up with an 86 on the second exam!
Don't kick your sister out of your chair :( (Love the videos!)
Lol! I wouldn't REALLY kick her out! Glad you enjoyed them
mam ur videos are amazing....keep uploading videos
Thank you! :)
Hey! Can you please explain this-4:43 shouldn't iodine with negative charge be more willingly to give electron due to its large size and thus be more reactive? Compared to fluroine
It's not a question of willing to give up a charge, they're holding on to their electrons. Instead we're looking at the ability to HOLD a charge. The larger I- holds the negative better (think bigger and stronger)
@@Leah4sci but isn't flourine more electronegative so it will hold on to tgat charge better rather then iodine
vid 1 of 2? More like "Very good, and this information is true!" 👍
Glad you like it!
@@Leah4sci I'm glad people are coming across these "puns" 😆
🇪🇬I'm watching you from Egypt, thank you very much
you're welcome
awesome
Thanks!
Obviously you are bigger and stronger. But don't kick out your sweet cute sister😁😆😅😂love her. I also love your vedios
:D No I won't.. she's also strong! :D :D . I'm glad you love the videos! All the best!
your videos are better than frank wong's
I think Frank is awesome, so thanks for including me in with him!
key take away from this video: size matters!
I like it! Thanks for watching.
Your sister defenetly gave you an dislike for that
haha she's a lawyer, I doubt she watched this
