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.
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?
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.

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.
@@strongbodystrongmiind Yeah, it did. Strong bases are not stable by themselves, so they will not easily separate from an atom/molecule (they will not LEAVE easily). Weak bases are fairly stable by themselves when not attached to another atom/molecule (in comparison to a strong base, they can LEAVE easily, hence a good leaving group).

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?

Got an A on my exam. Maybe not solely because of this video but it did help!
Glad you find it useful
I didnt want the video to end :( awsome job!

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
Turns out my toxic ex is a terrible leaving group... she never leaves me alone no matter how hard I try 🙄😂
Thank you! I enjoyed your clear explanations.
Thanks man, what about Phenols?
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?
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:

I found this video very helpful. ❤
very nice explanation 👍👍🙂🙂🙂
what program are you using in this vid? thanks for the vid
do you have a video explaining how you got that hydride as a LG?
Great video! Thanks!
thankyou so much sir...love from india sir!
OMG, I love you so much! Thank you!
Enjoyed your lecture....
Glad to hear that
It's very marvelous and interested
why is water a better LG than OHCH2CH2CH3 (an alcohol)? Thanks
+Julien Prégent
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
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
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.
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.
THANKU so much I enjoyed it

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
@@strongbodystrongmiind Yeah, it did. Strong bases are not stable by themselves, so they will not easily separate from an atom/molecule (they will not LEAVE easily).

Omg you are awesome....greetings from india..
I thought you were going to explain why they are good leaving groups not just give some common examples of good leaving groups
Thanxx a lot sir
You are welcome

the nucleophilicity of halogens actually varies with change in the solvent they are kept in
