Organic Chemistry: SN1 nucleophilic substitution

[jayisnotnormal]

only thing good..is the intro tune !

looneey tunes :D

[coolduds64]

It will be more helpful to concentrate if there is actual human voice rather than that crap music

[aamihar98]

star wars music?

[icefist101]

hey anyone know the name of the song played at the end?

[WillianCapille]

@icefist101 The last music played is "Breathe" by "The Prodigy".

[selalanurag]

ya thats true about racemic part thats incorrect and they forgot about hydrogen extra thats showing in there

[JulixHartley]

awful audio, or is that just me? I'm getting really bad quality for most of the video... :-S

[mokdadmm]

Very cool video!

I give it a 5 star *****

[aknight47]

awesome. music got me really pumped up for some chemical reactions! thanks.

[slLLyhumans]

Organic chemistry rocks !!!

[cowfordflorida1]

lmao at the darth vader music showing up when all the complex fucking pictures appear

[786sayyad]

a dfg vfs betrsh bhebt

[UOTLTube]

wow the soundtrack with the black background makes boring Organic Chemistry so intense...

[mdaj99]

Thank you very much , i found this very useful for my exam :P

[rehmsmeyer]

Yes, but in Soviet Russia, nucleophile bind YOU!

[devilishlog]

omg this is one is more funny then sn2

[thee1spleffy]

i always get confused with Sn1 & Sn2 but that video helped loads. thanx lol

[PeterCarneades]

Oh, I got only 95/100 in my Organic Chemistry exam this term. The highest score in my class is 96/100.

[clouddragon07]

still very good buddy

[teaterstigen3]

hehehe...ourbooks also start with sn2 then sn1..freetings from sweden!

[Agentoxedo07]

Holy-Terrorist:>1:28 style virus computer *=*

[Agentoxedo07]

Holy-Terrorist:>*=* HAAHAA

_=_ sepelache

[minime189]

thats ethanol... not methanol...

[h20fourlife]

thanks !!!

don't know why our book explains SN2 first and then SN1.

[LemtemPoktui]

Hmmm, i heard my sir said that Sn1 reactions is a reaction which only depends on the OH ions? Can anyone explain to me more?

[1006Will]

sn1 only depends on the concentration of the R-LG. whereas SN2 also depends on the [ ] of the nucleophiles.

[LemtemPoktui]

If so, why? Why does the sn1 only depends on the oh ions?

[mike80452]

It doesn't depend on OH anions at all because the slowest step in this 2 step reaction is the rate at which the leaving group breaks off. The base is forced to wait for this to happen before it can attack. It's all a matter of how many things there are available for attack, which is the [R-Lv].

[very80s]

hahaha, so funny. with this video I'm almost beginnig to like organic chemistry ....hmm... maybe not.lol

[nadiachicago33]

great song ! i love Queen 4 ever

[MarcusDiMarco7]

The music is distracting, but thx for the explanation (i just muted it)

[bboyadot]

great video final tomorrow

btw what's the second song? after star wars

[WoolyFox]

Prodigy-Breathe is the second song

[Johnny2B0]

it'S "under pressure" by queen

[nicklagard]

Protic solvents like water and ethanol are widely used in Sn1 reactions. Aprotic solvents like acetic acid are used in Sn2.

[gottalovesci]

has anybody taken MCat ? i just need some info ..

[KingofZona]

I have a weblink for the ENTIRE solutions manual for my current organic chemistry. Tell me what book you have and ill tell u if its the right one. I'll sell it for less than the price I paid for it!!!!!

[harlequin109]

Good examples but i would have used the arbon monoxide and the copper sulphate displacement

[PeterCarneades]

Is this a name reaction?

What is the mechanism?

[rolandogbg]

oh god i hate organic chem

[Blissbaby8]

This video made my Organic chemistry class a bit more entertaining:)

[PeterCarneades]

Our courses are book+blackboard, but I still like it.

[jessicadoucet1]

absolutely hilarious

[Agentoxedo07]

Holy-Terrorist:>*=* i know

[midoremilo]

how to download this video from here?? i need your reply by tomorrow. thanks. =)

[03452091001]

if you have real player new version then it gives you the option to download the video on the top right corner,

[yamamotojinftw]

you guys totally forgot about the extra hydrogen on ethanol that has to be deprotonated for the product to be formed...look at 2:15 to see what I am talking about.

[capefeather]

It was given in the final product, so I guess he assumed it was given, lol.

[SaamAzargive]

no you're right

the -OH group needs to be deprotonated in a final step. NO3- is a good example of something that would remove the extra proton with its' lone pair

[ROYALFLUSHyyz]

@yamamotojinftw yea... the ethanol should deprotonate the hydrogen in a final step

[jackphd]

With reference to SN1 reactions the part about "racemic" is incorrect. Where asymmetric products are produced there is usually a slight excess of one enantiomer. See "Weinstein."

[ochem9]

While you are technically correct, there is not an undergraduate school in the US that would ask a student to know that. For undergraduates, SN1 = racemic.

[Jack63815]

very ture. good video. i'm current studying chemistry with education and i reckon this will be useful in later years. thank you.

[LordNeel666]

I study in India, so I dont know what the corresponding level is the US (I'm 16). But isnt the reason why it isnt racemic quite elementary?

[PeterCarneades]

The leaving group can't escape the molecule at once. It will still block some nucleophile coming close from one side.

[03452091001]

yes inversion is slightly more than retention because the leaving group hangs around for a while before it leaves completely so the nucleophile attacks from the backside and u see inversion enantiomer more than a retention enentiomer.

[PaintballOO7]

@ochem9 Actually, Rutgers Orgo asks about that... I guess Rutgers just goes all out when it comes to Orgo!

[Choosnumber1fan]

@ochem9 Incorrect, we have to know it for my Organic Chemistry class at the University of Texas Austin

[blakebay]

@ochem9 I wish you were right; we have to know it for organic classes at the University of Georgia

[soccerman1434]

@ochem9 Not true. And why would you bother learning a half-fact?

[Masteroftrancegirl]

backside attack baby!

[GsKillz818]

too bad it isn't.

[elmusicandi]

Well it was ok. Org. Chem. RULEZZZ !!!

[xxxsourgurlxxx]

i like organic chemistry and it is soooo fun. and i found this video confusing basically because of the music that is used. that makes it complicated. :D put somethin fun!

[GsKillz818]

the product is actually not an exact racemic mixture. The result favors the inverted configuration about the asymmetric center because right after the the leaving group leaves it can get in the way of the nucleophile to attack that same side. Even thought the reaction is not concerted, it prefers the inverted configuration.

[ccr61851]

could you explain that?

[Renmarker90]

he just did =)

[nb1001]

ah ok, i was going to say that the nucleophile bonded in the wrong spot, but when flipped you can see where it rly bonded, thanks, helpful.

[Paedomorphosis]

I thought it was hilarious. With the star wars theme and serious songs.  I was routing for the underdog the whole time though...I was hoping for an E1 reaction

[ponchaz1]

Nice video...i love John Williams
