Lewis Diagrams and VSEPR Models

[@dayyuumabby]

wow, an AP chemistry teacher explained VSEPR modeling in 12 minutes better than how my professor (PhD in chemistry) has been trying to for the past week. YOU ARE A LIFE SAVER!

[@slightlygruff]

Change the uni

[@tangytoby]

You have been the best teacher i've never had. I've wathced your videos from grade 9 all the way to university. MANY THANKS !!!

[@M3madness25]

First of all, YOU ARE AWESOME! Thank you for posting all your bio/chem videos, they are literally the only things that help me make any sense out of all the things I'm learning in college. Obviously your invested in teaching! I know your a teacher and probably have a lot of work, but your also a saint for a lot of other people. Please consider posting a video on hybridization going into depth of the sp, sp2, sp3, sp3d, and sp3d2 (in terms of spins and how to determine they are sp, etc), their shapes, and how the sigma bonds and pi bonds interact? Also a video on Molecular Orbital theory would really save my life (and I'm sure many others). Thank you!!

[@PrivateYoutubeAccount69]

+Shivanshu Siyanwal No too late for me ;) Thanks!

[@notsocooldude7720]

Thank you. My chemistry teacher talks in a monotone voice and is terrible at teaching and I learned way more in this video than 2 hours worth of class.

[@fatmouth007]

Good luck on your midterms everyone - ride the curve, but don't count on it!

[@XVII-NUM]

i failed it :D

[@pullingthestrings5233]

Got a 99.71% on my exam

[@Ambi1021]

I had to subscribe. My professor needs to take notes from you. You make it so easy to understand.

[@AyamGolek98]

this is really helpful when i happen to absence in class when the lecturer explaining this theory.thank you sir

[@tannercole7905]

Thank you SO MUCH for helping me pass my Chemistry class! You are such a big help!

[@caitlin13osullivan]

I took AP bio last year and my teacher showed me your videos. Im in AP Chem chis year and im so excited youre making chemistry videos now!

[@KlacByKenneth]

Thanks so much Mr.Anderson, your videos really helpful for the Pre-U students in Malaysia :)

[@mspiz6082]

This was so helpful, and you explained it in a way that made so much more sense than when I learned it in class. The example of the balloons really helped me visualize the structure! Thank you!

[@ItsYaBroMo]

for 3 years you have helped my thank you thank you

[@littledreamerrem7021]

University student here. Thank you for explaining this properly. My professor, he mentioned Lewis structures in passing, and only barely defined them. And I do mean barely--until earlier this week, I thought they were the same as electron dot diagrams. Yep. He didn't even show us any examples of Louis structures that couldn't be mistaken as an electron dot diagram until yesterday, much less show us how we would get that witchcraft out of a chemical formula... Oh, and did I mention that we have an exam tomorrow? The school tutoring folks have no clue what he's wanting us to do in the review problems half the times, too...

[@926starburst]

When watching this video, I kind of expected that many of you guys in the comments may feel that he was going really fast. And I thought he went way to fast but luckily I already knew most of this material. This shows that many of you guys in the comment sections are smart!

[@delaineyarnold4403]

chemistry makes so much more sense after watching your videos! thank you!

[@harissohail5739]

What my teacher teaches me in 4 1/2 hours you teach in 12 minutes. Ur acc goated

[@romeomavuso2105]

Thanks sir...tomorrow im writing a chemistry 111 test and I didnt understand a thing here but you have more than clarified it for me

[@faidintoyou]

this mans been w me ever since AP Bio and now chem

[@absian4426]

omg, professor, you are awesome!! You saved my test!

[@shockoboy4421]

Thank you so much Mr. Andersen. The explanation was clear i really understood what you taught thank you so much.

[@allyssaacosta6974]

Im not going to lie, Im in University level Chem. and your videos make more sense to me than when my professor explained it. Thanks i would have wished that you explained it further but Good job,

[@azimuthzero7814]

Thanks! That balloon analogy really helped my comprehension :D

[@vasquezg86]

Thank you, Mr. Anderson, Sir!!!! Great job at explaining everything

[@valfastenau3891]

total lifesaver!! love the videos and super helpful for my college chemistry class

[@5uraj_Rao]

Am I the only one who thinks he looks like Hank?

[@xxmojoballsxx1550]

yes, Mr. White

[@jonweinraub]

Can you get more intense with the videos to help folks in general chem 2 (and beyond) in university? It is amazing though how much high school AP chem goes over in a second semester college course though!

[@rainbirdp]

Excellent, succinct explanation.

[@pkenterprise3110]

Bhut accha notes hain sir ji log ty fr uploading this video

[@MachoFrogg]

Thanks to you i got my homework done :)

[@sanjeevshrivastava5927]

you are really awesome in chemistry. I follow you to learn easily.

[@smaransandri1608]

Great explanations! Perfect way for teaching students. Thank you very much sir. :)

[@dreamdrops3788]

Ah thanks, filled up some gaps in my understanding. Social anxiety so I usually tend to hermetically try to figure out any gaps than approach (physical) people.

[@ethanalfred2154]

DreamDrops same

[@imsmallcat1034]

Pussy

[@sciencenerd7639]

a very nice review, thank you

[@Felipe-53]

Hey, thank very much you for your videos. Helps A LOT.

[@ayahabdelgawad2850]

Very digestable and understandable

[@claudiapalacios8824]

this helped so much, it was a nice review!

[@747station]

You, sir, are awesome!

[@kayla18g23]

This really helped me, thanks!

[@Bob50520]

MR ANDERSONNNNNNNNNNNNNNNNNNNNNNNNNNNNN.. ohhh yeah :D thanks for the videos, much love from canada!

[@FedorKai]

Thanks to you i may have a chance in tomorrow's test lol

[@tasnimnur4833]

GREAT I COULDN`T UNDERSTAND A THING AT FIRST!!!!!!!!!!!!!!!! UR AWESOME THANKSSSSSSSSSSSS

[@viduradurina2149]

Thanks for this video it really helped me.

[@ziontea6559]

I love your science videos

[@Khanceited]

THANK YOU!! i finally get double/triple bonds now

[@dheeraja570]

wow such a great video it"s really helping a lot

[@nancym5494]

At 11:22 why does nitrogen have only one odd electron if three are bonded with oxygen and it has 5 valence electrons? Shouldn't that give it 2 non-bonded electrons?

[@lifelyrics5659]

Love your videos as always! But yes octahedral and trigonal bipyramidal angle is important

[@JaxSG9]

Thank you for a great video

[@palvisharma7259]

SO HELPFUL! THANK YOU VERY MUCH :)

[@kakashi8764]

thank you so much sir! :D :D thankyou!!

[@Bozemanscience1]

No problem. Best of luck with your studies.

[@lenas3820]

Thanks this was soooooo helpful!!!!

[@ambikannan136]

Vry well explained sir....can u explain abt: what is an excited state , ground state and hybridised state?

[@shaimaahagag7887]

thanks alot... ur such a great teacher...however it would have been great if u've streesed on the difference or why co2 and O3 have different geometries while they both are triatomic molecules... but good job and thanks again u realy helps me alot :)

[@nightwalk3132]

thank you so much sir!! i love it.

[@AmanDahiyaOfficial]

you're amaaaaaaaaaaaaaaaaaaaaazingggggggggggg!!!!!!!!!!!!!!!!!

[@andreavictoria9181]

At 6:12 what do you mean by 6 minus 1 for the formal charges?

[@ThePianoManP]

did anyone else notice in the first example that nitrogen has 5 valence electrons, it's sharing 3 so 5-3 wouldn't that be a formal charge of 2?

[@johnthiele5957]

+Luis Carlos Zero is correct but I don't think he explains in this video that nitrogen's 2 non-bonded electrons are also counted as assigned electrons so 5 v.e - 3 from the triple bond - 2 non-bonded = 0

[@rxysurfer11]

This was AMAZING. I wish i saw this video before i failed my exam :( ugh

[@Alyssa-sw9iv]

Thank you so much! Just one question... When you are bonding CO2 for the lewis structure you used one single bond and then a triple bond. Would it be wrong to do a double bond on each side of O=C and C=O?

[@shindehoshi4470]

thank you! i'm subscribing!

[@sollinw]

I love your contents

[@brianvuong97]

Can you review the formal charges and explain why the first oxygen loses one and the second oxygen gains one?

[@926starburst]

Brian Vuon an easier way to think about is how much valence electrons does Oxygen have.... Well it has 6! When Oxygen is single bond to some central atom, say Carbon, It will be using 2 of those electrons. So you count up the electrons that Oxygen uses and then you take that 6 we figured out on first part and subtract...

[@factzilla3071]

At 7:08, couldn't the middle O have double bonds with both of the outer O and maintain neutrality?

[@Ange-or2np]

5:05 I thought nitrogen usually had five electrons and when bonded in HCN had 4... So wouldn't the formal charge be -1?

[@pirateos9676]

yes, I agree it should have formal charge of -1

[@glenjnr10]

This can be more clear if you add the lone pairs for carbon before adding the extra bonds

[@legendaryomali]

Thank You very much!

[@azhar4722]

Much love

[@decryptthestory861]

The only thing I don't really understand is with the O3 example, why don't you give both the outer oxygens a double bond? Wouldn't that balance all the atoms with 6 electrons?

[@sumisumi.parvin.5534]

in your channel, have you made any video for stabilization of carbocations?

[@mayelimendozachavez9019]

I have relied on mr anderson since freshman year

[@JJ13..]

Why is it -1 when is sharing one but +1 when is sharing three? 6:13

[@britnih5619]

i know youre geared for ap but still very helpful for college level :)

[@anithaonesmo1482]

more than helpful

[@Doorknobperson2]

Why did N have 6 lone electrons in HCN initially? It only has 5 valence electrons?

[@anmolsen5341]

When we can keep the formal charge of all the oxygen in ozone zero which is also the favorable condition as you taught then why we had to end up in resonance....

[@aroz945]

Hug? No? that is ok I love your teaching Thanks :D

[@sarakm9595]

Thank you thank you thank you

[@wow846]

love u paul

[@DJAliMokhteh]

at 10:08 he said PCl4 where it should be PCl5

[@emilyroberts851]

Why did O3 have charges? It looks to me like there are 8 attached to each of the elements. Am I missing something?

[@noahholloway8702]

It's based off of how many valence electrons the atom has (without bonding to anything), so for example the first oxygen has 7 electrons - 6 valence = 1 negative charge.

[@francisfullwood3330]

I have a question for the Ozone part. if i draw 0=0=0 with 4 electrons on each side and 2 in the middle... does it work??? cause when I do the R, its all 0 (6-6=0). So i don't have a +1 or -1

[@Clints89]

Francis Fullwood if you have a double bond on both sides and two attached to the middle it violates the octet rule.

[@AceDRoses]

But SO2 does that and has the same valence electrons and it works. And theres cases besides the exceptions that break the rule no?

[@Crunchyapples1]

Does the trigonal bipyramid models not satisfy the octet rule???

[@sachinshah8099]

+John Kim Yes

[@chiamakaokafor8761]

I don't understand how you did O3. Can someone please explain?

[@AceDRoses]

Doesnt the N in HCN have -1 formal charge? It has 5 , but it shares 3 and keeps 2. Isnt it +2-3?

[@ArifeenSaeed]

Thank you~!

[@iGeeJay]

Why is O3 not double bonded to both?

[@psychenihil5415]

Didn't really understand how we got the shapes...

[@sydneythayer8831]

Is it a coincidence that you started by drawing a Lewis structure of HCN? Because in a previous video you mentioned that it's speculated that Lewis committed suicide by (hydrogen) cyanide. I have a feeling you did that on purpose lol

[@MrJMont21]

Is it possible to have hydrogen cyanide with only a double bond between the carbon and nitrogen?

[@alirezaizadi1263]

thanks a lot sir :->

[@melissacamden1949]

Why can't you bond the electrons from the middle O in Ozone to the O to the left so that the middle has all bonding pairs??? so its like ::O=O=O:: ?

[@melissacamden1949]

If by that you meant the middle O with the 4 double bonds would give the compound a 0,+2, 0charge, rather than a +1, 0, -1 neutral charge... then yes.

[@WeSnapple]

didnt cover bent molecules why?

[@ashekai2545]

'Cuz he couldn't really represent it with balloons I guess. It would look weird. Unless you were talking about what the degree of angles are...you can probably google that.

[@noevillarreal9756]

For the O3 wouldn't ::O=Ö=O:: work? (imagine the electron pairs on the outer O's placed correctly. Sorry.)

[@ayahabdelgawad2850]

+Noe Villarreal The O in the middle would have 10 e- that way .. you only need 8 to satisfy the octet rule

[@bockman55]

thanks

[@ifonlycainwereabel2110]

No sp hybridized in ap chem? Why am I learning in in ap chem tho? Lol

[@thicc0rita69]

Cause that's back in 2013 and you're asking him in 2018??!?! Syllabuses change every 2-3 years in every curriculum. :)

[@iGeeJay]

When ya got a quiz in a few hours

[@chidoan5269]

Uhm apparently in my ap chem class hybridization does matter...

[@HAMHAMS110]

This video is loading incredibly slow for me, is anyone else having this problem?

[@sydney7354]

Why does this man look like Hank Green and Mark Pellegrino had a baby???? also thanks for the lesson Lankcifer!!!

[@simeonjames7584]

Good u guys
