Got an A on my exam. Maybe not solely because of this video but it did help!

[KaA]

I didnt want the video to end :( awsome job!

[geraldomedrano]

Thank you! I enjoyed your clear explanations.

[triforcejj]

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.

Awesome. Glad to hear it, good luck on the next one!

Turns out my toxic ex is a terrible leaving group... she never leaves me alone no matter how hard I try 🙄😂

[quizilla]

thankyou so much sir...love from india sir!

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?

[julienpregent]

why is water a better LG than OHCH2CH2CH3 (an alcohol)? Thanks

[strugglingcollegestudent]

do you have a video explaining how you got that hydride as a LG?

[maixiong]

OMG, I love you so much! Thank you!

[anp]

what program are you using in this vid? thanks for the vid

[harrisoncollege]

can someone please tell me whether the tosylate or chloride ion is the better leaving group please?

[GatlatDoyaknguth]

It's very marvelous and interested

[roteme]

 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?

[sandursantoshkumar]

but why are weak bases better leaving groups?

[adosar]

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.

[TheIraqiforce]

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?

[azzie]

Omg you are awesome....greetings from india..

[rolando]

I thought you were going to explain why they are good leaving groups not just give some common examples of good leaving groups
