SN1 SN2 E1 E2 Reaction Mechanism Overview 

Another clue is that E2 rxn will always include heat. Any reaction done in a turtbutoxide is also usually E2 . The formation of the Tertiary groups in an SN2 reaction crowd the electrophile and don't allow the nucleophile to come in but it can still be possible for E2

In 7:29 minutes, you managed to calm all my anxiety for my up coming exam. I am eternally grateful for your videos. Thanks.

I'm learning more I feel from these kinds of videos than all my classes.

This was such a clear, concise, and helpful video. Thanks a bunch!

u r literally the best. you can explain things that i don't understand in a 2 hour lesson with my teacher!!

Hey, I just wanted to thank you for your videos. Because of watching them, amongst following a lot of other study habits, I was able to get an A in Ochem 1. *Cheers inside.* :)

This is the best, most straightforward video I've seen on the topic

Can you believe I went through ochem1 without even memorizing this? In ochem2 and failing. RIP me

Your videos are so clear and easy to understand. Thank you so much!

Wow I just learned this today and then your video comes up... THANK YOU

I cannot believe it was this easy. I was almost going to cry because I couldn't understand the concept 🤧 thank you miss ❤️

Perfect explanation, thank you!

Highly appreciated for concise and clear explanation

Great overview before exam !! thanks for your help

This video may save my life for my recitation quiz today. Thanks!

This is the best video explanation of this topic!

Thank you SO much for these!

It made me understand almost everything :) just how do you know where to get the H from in e1 and e2 reactions?

Thanks to U! An excellent short video.

this is so helpful, thank you so much!

thank youuuuu som much , i can't thank you enough for this. finally i understood it , you are the best.

Very good introduction to SN and beta elimination reactions imo, good job!

You are amazing! Love your videos thanks so much!

The only video i could find that explains the diffrence between E1/E2 and Sn1/Sn2 Reactions, thanks

Absolutely perfect quick little review before my exam

Very grateful for your videos! My professor reads from the book during lectures so your videos are a tremendous help. Thank you for sharing your talent and knowledge!

Beautiful video! I think the concept of stereochemistry inversion should have been brought up using chiral examples, but it was really informative regardless.

thanks, my organic chemistry teacher is really helpful, but in addition, this video was great for me to review for an exam

7 years later and its still helping people with exams! This was a great review for my Ochem Exam this afternoon, Thanks!

this video is incredible. thank you so much

Leah u are a lifesaver

It's exceptional..... I like it. Thanks.

Very informative and helpful

Thanks for a video its helpful very much

Very nice explaine organic chemistry thank you . 👍👍👍👍👍 from ethiopia 🇪🇹🇪🇹

thanks for the great summary

This is so helpful!!!

thaanks for the video it helped me a lot :)

thank you leah

thanks a bunch!

I learned more in this seven minute video than I have in a month in my class.

like before I watch it ❤

good explanation, thanks

Just watched every single vid for this series that night before my final. Just now learning this. Rip.

This is such a cool idea and great video! I'm a chemistry prof in the US working on a similar approach on my channel. I like breaking down the concepts by videos, and giving an introduction to a topic (e.g., Assigning R/S stereochemistry) in 5 min or less!

This is helping me a lot I was so confused

I struggled through Ochem 1, so I’m reviewing during my summer off so hopefully when I go back at the end of August I’m better off for Ochem 2 😬

Nice video and thanks

Very Useful , thanx 🌺🌺

I have a test tomorrow and I'm comping on your RU-vid channel Thanks alot ❤

Leah4Sci wherever you are today, thx you girl and I hope you are a great doctor/scientist today xoxo

Hey im so weak in organic chemistry and in want to make it perfect especially rxn meachanisms

Thank you

Thank you teacher

Thanks a lot ma'am

Cool videos and very helpful... 😉

Another amazing video I wish I found sooner. You are my go-to for organic chem info!!

wow thank you sooooooo much !!!!!!!!!!!!!!!!!!!!

So thanks 😍😍😍😍😍😍

Does heat always help favor an elimination reaction, or does it depend on the nature of the base?

Using all your Materials for the DAT.

For the E2 reaction, wouldn't the most substituted Beta-Hydrogen be the CH3 on the right of Cl ?

hey dear mam I love ur teaching methods

Great!

god bless you!

Amazing

Good video, on-time! :D

God bless you

Very nice

You're amazing

Nice voice editing.Seriously, I m in love with your voice.

you're a godsend

best video less time...more knowledge

Watching it for jee really helpful thankyou ma'am..❤❤❤.. ive some doubts regarding it how can i contact you

what does the H+ ion do in SN1 ?

Why does heat stabilize the pi bond formation?

im sacrificing this section for tomorows paper, i just dont get even after watching alot of videos i just cant!

The dehydrobromination of isopropyl bromide requires several hours of reflux with alcohol KOH whereas in t.BuO-K+ / DMSO, dehydrobromination can be carried out in less than a minute at room temperature. Why this is so?

❤❤❤❤

best fucking video i love you bro

Why would chlorine leave the carbon atom, in the first place?

👍👍👍👍

Miss can you make online classes on organic chemistry using google meet

What about SNi and E1cb???

Umm why sn2 are called bimolecular i can only see br and that's only 1 molecule reaction

Madam, Still the modulation not your explanations linger in me. 👆👏👏👏👏🥰 Am a small Tutor in KERALA STATE, S. INDIA

My teacher took 6 days (1.5 hrs daily) to explain

ma'am, thousands of students including myself owe you their tuition fees

You are Jesus.

My final is in five days. My prof never taught us any mechanisms - just to memorize the reactions. I want a refund. Thanks Leah!! I've sent my classmates to your channel.

00:38 Are we gonna ignore the fact that you have a strong acid (H⊕) as one of your reagents? :q This means that someone should get protonated before anything else could happen. The only candidate for protonation here is the alcohol, but once it gets protonated, it won't possibly be able to act as a nucleophile. Before protonation, it was a weak nucleophile at most. After protonation, it would be even worse, because of the positive charge it would get. And this positive charge would make it keep away from the also positive carbocation. So besides protonating the alcohol, I don't think that you'll get any SN1 reaction here. Another problem with this acid is this: _which_ acid in particular? In these type of reactions, solvents are very important, so you must be specific, because depending on the acid, there might be a different result. If you used hydrochloric acid, I don't think that the chlorine from the tert-butyl chroride would be so eager to leave the molecule, considering that this would increase the amount of chloride ions in the solution, and Mr. le Châtelier might frown upon it :q The acid actually seems to be driving the reaction in the opposite direction, making the molecule more stable as it is. The fact that you got negative charges on stuff in an acid-catalyzed reaction should already blink some red lights. Because acids tend to get rid of negative charges as soon as they appear, or don't let them appear in the first place. And the fact that you started with an acid catalyst and didn't regenerate it at the end, is also kinda sus. And lastly: why an acid at all? The alcohol can act as a nucleophile as it is (definitely better than if you protonated it). Sure, it is a weak nucleophile, but still a nucleophile, and it can attack a strong nucleophile (such as the carbocation left beind the chloride as it leaves the molecule) just fine. It is also a polar protic solvent on its own, favoring the SN1 reaction. BonBonus point: atoms can't just fall off "on their own". That would be very unfortunate for chemistry and stability of matter in general :q And they can't just "choose to leave" (regarding your reply to someone else), because atoms are not persons, they don't have their own mind and they cannot "choose" anything. They can be _made_ to leave by some external factors (in this case, the solvent).
