Chemistry 3B - Lecture 03: Electronic Spectroscopy

[Lesterernesto]

thanks U.C Berkeley for putting back the 3A in the webcast... thank you very much !!!

[LemonLimeLaughter]

I have no idea what he is talking about

[denChemiker]

The title is deceiving! As a pchemist, I was really hoping for a spectroscopy course, but this is just simple organic.

[iamaar0n]

Though I'm sure many will reference Loudon in their course study, I'm guessing the text suggested for this particular class would be Organic Chemistry by Peter Vollhardt (i.e., the INSTRUCTOR'S textbook.)  :)

[12stringovation]

Thanks

[12stringovation]

Anyone know what text this class is using ?

[ryanhall2013]

@12stringovation  You Fail! lol...... j/k

[kirkindysolospock]

I enjoy the UC Berkely lectures, I watch as many as I can.

[xjkgx]

disliked the lecture...not enough examples or mechanisms to understand why

[algeriano99]

good i like this

[TrutherD1]

Check this. There's a secret aerosol program going on worldwide causing thick overcast every day! It's chemicals. I filmed it myself (my chan). Search for "chemtrails", "Dont talk about the weather", "Endgame HQ". We need to wake up and wake others to stop this!

[bellinivernon]

Exelente ! ; gracias ,desde argentina.

[Blackmetalstudios]

Holy crap I lost the thread after 1 minute.

[Chumpster9]

Thank god I'm done with Organic Chem haha

[Naam19]

I can't find 1 and 2 either.

[mad27]

Watching this makes me glad I'm a Political Science major. lol

Go Bears!

[futureneurologist]

lame.

[gades21]

Where is the lecture 1 and 2?

[ilovemark81388]

they were probably intro classes, like handing out the syllabus and getting to know each other

[gades21]

Where is the lecture 1 and 2?

[xjkgx]

ladies and gentlement if you dont speak the language...stay the fuck out u either get it or dont

[ACrockers]

is there is any scholarships that can give to sri lankan students in the filed in medicine

[panefuldeath]

Not for ones that can't spell.

[JadenYugiGX]

Useful somehow.......... Quite Booooooring

[czarevnah]

hey thanks really helped

[HelloBrainMind]

hes spitting out chemical names expecting these kids to know all these... Not a very good teacher. Does he realize these kids are probably sophmores or juniors in college, and not grad students, and have little to no organic chemistry knowledge? JEEEEEEEEEZ

[saturday7142007]

This class is for undergrad sophomores. There are prerequisites and there is assigned reading. That is enough to get through lectures (or sleep through haha!!).

[palos31]

For sure you are product of the american educative model.

[HelloBrainMind]

For sure you think you are superior to americans. Congratulations on being the stereotypical immigrant that insults americans, then comes to study in america.

[palos31]

somebody must take advantage of those excellent teachers. And please dont cry, USA isn't perfect. Is a great country, I know, but your elementary school sucks.

[HelloBrainMind]

Our middle through highschool is in need of advancement, yes.

[jessiep02]

Actually, this class is 3B which means the students should have taken their first year (or at least 1st semester) of general chemistry and first semester of Organic chemistry. In those classes, you learn the terminology. So you should know the compounds and terminology. However, though he uses a lot of jargon, he's really good at explaining exactly where it is coming from (ex, review chapter blah blah where we learned so and so). The class is still hella hard though.

[LeeDiddy990]

organic chem is needed no matter whch major you are taking wheather its chem. engineering, bio, or a chemistry major. although its more applicable in chem. engineering and pharamacy then medicine and biology.

[fedaai]

great ..

thunx..

i'm a student of chemistry also in university of bahrain

[pinkgurlie1881]

can some one help me make this x or not

[TheSuperDevil]

followed most of this but quite a bit went over my head.

but then again i am only 14

[Mattprole]

I see this quite often; why do so many younger people viweing feel they must voice their age? As if it proved them a genius to a mass of unanimous intellectuals...

[Cheesewookie]

It doesn't take a genius to understand this stuff. I did say that quite a bit went over my head.

hmmm...

feeling old are we?

[kidoleyangu]

going over your head doesn't always mean understanding....sad fact!

[lordnikkone]

good.. it's not like the chemistry class. i took .. where my professor relay more in the reaction mechanism or synthesis ... and the you can only has to understand.. this reaction..

[rockshow6]

hmmm, i dont take physics and iv understood with ease the physics lectures, i take chemistry and just cant comprehend anything hes saying...

time for a switch in disciplins?

[boybrolic]

You will not use these rxns in med school. THANK GOD I made it through orgo though! As long as you familiar with orgo that's all you need to get by. Even then, the only time you'll see anything relating to orgo will be in pharm. That said, enjoy your orgo! HEHE!

[mehdan2]

I think this is in Latimer 102. Cool place.

[nvmcxzoiusae]

@mehdan2 Nope, 1 Pimentel.

[Associatedfan]

UCB where is lecture 1 and 2 ?

[luvmonkey666]

could someone tell me how i can seperate NaCl (salt) to just get Cl and then maybe make it into a liquid for cheap pool chlorine

[azngamer828]

I am not sure if this is right.

But dont you mix it with water to make NaCl dissolve making the Na fuse with OH.

I wasnt sure if thats rite.

sorry

[ItamiHikari]

I guess you could dissolve it in water and then use electrolysis to gather Cl-anions at the cathode...

there is an electrolytic cell on the market which is especially made for cleaning salt water swimming pools. It works marvelously. Maybe you can try that out...?

[Jacknast08]

Maybe electrochemically. But it is much cheaper to just buy the stuff

[luvmonkey666]

well bags of salt are alot cheaper than pool chlorine

[xjkgx]

you cannot separate salt like that...it is ionic in nature and would require you to fulfill the ionization energy of NaCl...you cant do it in solution either....the only way of doing it is to MELT the NaCl and then run the appropriate amount of current through it as to separate molecular Cl from Na and youll get sodium metal and chlorine gas as end products

[tinobeanoweano]

Brilliant , Just Brilliant ! !!

[eldali180]

thank you ucberkeley you are great

[ColectvIndvidulism1]

Interesting vid. Thanks for posting it.

[UruEco]

wow . i like this I can learn so much here

[ssorenn]

aha, yes...reactivity of the alkene when hydrogenial bromination of eletrophynic additions occur, yes

[commanderak]

Can someone explain me why at 8:30 in the blue aromatic ring of the product, the double bound is "the point of the arrow",

while before the reaction it is directly opposite the double bound that is sprung open.

This blue double bound is clearly not involved in the reaction, so why would it change position?

[pirejknf]

Yes, I think it looks like they made a pedagogical mistake. But I don´t think it matters that much for the actual product, since it is symmetrical.

[marcevans22]

wow. I have no idea what he is talking about

[steelystan]

Wow now I can go to an Ivy League college.. for free.

[peacetoker]

UC Berkeley isn't Ivy league...

[steelystan]

I know.. you passed the test.

[wolfhunter0321]

If UCB is not Ivy league, then what league is it? How, could any school, other than Jules Vern's school of fish be in a league without being all wet? :)

[charliepeke]

U.C. Berkeley is Pac 10. Their academic and sports rival is Stanford, which is also Pac 10.

[frontin2438]

maybe not like the traditional east coast ivy league schools but UCLA and UCB are easily competing and becoming pseudo ivy league universities in the west coast. Don't disregard these great universities just because they werent founded in colonial times or from the east coast

[charliepeke]

Yes. The Ivy League is actually an athletic league, like the Pac 10 or Big 10. Berkeley is more prestigious than many Ivy League schools. Maybe I'm showing my Alum pride, but you can check the academic reputation in U.S. News and World Report.
