Got an A on my exam. Maybe not solely because of this video but it did help!
Thank you! I enjoyed your clear explanations.
I didnt want the video to end :( awsome job!
Glad you find it useful
Very clear video. Only problem is the pka table. Our prof doesn't allow a pka table, explaining to me we should "know the trends of acids and bases" this is extremely frusterating when it comes to nucleophilicity and leaving groups as they are correlated with basicity.
how did u do
Awesome. Glad to hear it, good luck on the next one!
I love your video just wish that your website had practice that had more free worksheets but these videos work okay
OMG, I love you so much! Thank you!
Great video! Thanks!
Thanks man, what about Phenols?
You explain things so well!
That's kind of you. I invite you to check out membership opportunities awaiting you as well! Check it out here:

Thanks so much for the videos!!! I have an exam tomorrow,
how do I determine which leaving group will make the fastest reaction if Im given a few options?
The strongest acid will also make the reaction be the fastest?
If the conjugate acid of a leaving group has a low pka value, it will make a good leaving group.
I found this video very helpful. ❤
Turns out my toxic ex is a terrible leaving group... she never leaves me alone no matter how hard I try 🙄😂
do you have a video explaining how you got that hydride as a LG?
very nice explanation 👍👍🙂🙂🙂
what program are you using in this vid? thanks for the vid
A good leaving group is one that decreases the free energy of the products. A good nucleophile is one that increases the free energy of the reactants. So how it is possible iodine ion to be a both good nucleophile and leaving group? Thanks in advance.
thankyou so much sir...love from india sir!
THANKU so much I enjoyed it

in the pka table water is shown as a poor leaving group, but right after it's shown as an example of a good leaving group (?) so which one is it then?
It's very marvelous and interested
Thanks
You rock!
Enjoyed your lecture....
Glad to hear that
Thanks a lot!
you're welcome
why is water a better LG than OHCH2CH2CH3 (an alcohol)? Thanks

h2o is made from stronger acid h3o+ hence a better leaving group
oH- is mad from h2o which is weak acid and hence weak leaving group
Omg you are awesome....greetings from india..
can someone please tell me whether the tosylate or chloride ion is the better leaving group please?
Tosylate is actually a better leaving group than chloride.
Kami Dee because of the resonance OTs is more stable
I thought you were going to explain why they are good leaving groups not just give some common examples of good leaving groups
Thank you

but why are weak bases better leaving groups?
He said that weak bases are fairly stable even when they are not attached to another atom/molecule. A strong base is not stable by itself and so will not separate from an atom/molecule easily.
nizzle1931 that didn’t answer the question but ok
I thought as we go down the periodic table the nucleophilicty of our species increases, so why is iodide and cl- good leaving groups eve know they are strong bases?
the nucleophilicity of halogens actually varies with change in the solvent they are kept in
@@_n9652 Thank you I needed this after 4 years lol you brought back memories
@@TheIraqiforce no problem
Thank you sir
Welcome
Thanxx a lot sir
You are welcome
