Jahn Teller Distortion - Very Important

A detailed discussion on Jahn Teller Distortion. After watching this video, you would not feel any need to refer any book. All topics covered..

[@elishiakershom2020]

It's 1:54 am in the morning and getting a clear concept about Jahn Teller distortion has become "a dream come true thing" to me. Thankyou for your efforts. Your English is pretty good and easy to understand. Please post more.

[@purumansinghrathore4174]

Very useful for exams ... U r doing a great job.... Thank you.... We all belongs to chemistry and we need people like you who can provide quality education

[@niteshshivhare7208]

d5 low spin will also Show JTD bcz it is electronically triply degenerate

[@asitdutta3045]

t2g orbital isn't much JT sensitive compare to eg orbital so d5 low spin do not show JT

[@eddie01187]

d^4 high spin should show z-in distortion (compression). For HS all the four electrons won't occupy dxz and dyz orbitals. Sir, pls clarify it.

[@mzamoshabalala7166]

I like the way you present this beatiful concept, no paper on your hand, if we can have more people to do it in this way, then our education will be much easier. Thank you sir that was really great.

[@invalidusername1239]

Great job, u gave a detail explanation

[@yatendradwivedi2136]

thankyou...its my seminar topic....really helpful for me....

[@MohitKumar-sf3rc]

Sir, you are doing great work. I very much appricaiate your work.

[@chandrikakasina8405]

Sir, tq so much for ur classes I cracked IIT JAM 2019 due to ur classes

[@shilpab.kulkarni2101]

Share your study methods,plan and notes or books u used

[@Leo-xr2et]

Thank you sir for sharing your knowledge in a simplified way this becomes very useful for me sir, i am going to seat in the upcoming net june'18

[@sunandamitra1700]

Thanku so much sir..ur way of making d concept clear is amazing

[@RedDevil-vk9pn]

Thank you so much sir you are doing a great job ur videos have been of great help

[@devigagovindan6943]

Sir u the best chemistry teacher i have ever seen.... Tnnq so much....

[@ahilyakadam5658]

Thank you so much sir for clearing the concept of John-tel-distortion...

[@rahulsharma-vd7hp]

Thank u fr the explanation...thank u very much...it clears many doubt about the concept...thank u very mucj

[@heenaagarwal4631]

Sir in d4 low spin nd d5 low spin complexes ,which one will be preferred more Zout or Zin...????

[@sheikhabdulrehman3993]

thank u for the explanation,both on jahn teller and group theory

[@simplechemistry8761]

The z out and z in you draw for d4(H.S.) it should be d4(L.S.) as the 4 e are in the t2g set.

[@Sunnysideup0709]

very good explanation ☺️keep up the gr8 work

[@gaurangdandwate7268]

For d4 low spin, wouldn't two electrons get filled in dxy and two in dyz, while dxz remains empty due to pairing? Because, you showed that xy has 2, yz has 1 and xz has 1. Would it still be considered asymmetrical?

[@devendramishra603]

Thanks for wonderful explanation. Is there any trick to identify whether complex is high spin or low spin.

[@manjulgondwal3321]

thank u sir for all videos...I m huge fan of ur videos...great job sir...

[@mudejayaprakashnaik2365]

Excellent video...Thanx. Do more videos on other important topics ....

[@sohinigupta1999]

Far better than our inorganic teacher at IIT kgp.. Thanks 🙏

[@vijayamaurya2991]

sir I have a question ... what will be the total degeneracy of tha ground term of cobalt +2(HS) in octahedral geometry?

[@sudheer2643]

Sir Thanks a lot sir From now I get a clear picture and idea about John teller distortion

[@soulfulguitar2349]

Your videos r worth watching for jee advanced

[@Ayra7862]

Sir, for d4 HS if it undergoes z out distortion with 4 electrons in dxz and dyz then what about d4 LS ? Please check it .... I think among 4 electrons 3 will occupy dyz and dzx and one will occupy dxy ... please check ...

[@athulyaprakash8658]

thanku sir 😊 your video makes the topic very intresting

[@sandeepkumawat4982]

So what is the meaning of 1/3 and 2/3 energy..

[@vijaypandeychemistry]

Sir mind blowing topic clearances. ...pls continue according to csir....

[@rasayangyan499]

Can you tell me about the careers in chemistry for high paying jobs o

[@bijayapathak8271]

Didn't get the high spin d4 part in Z-out. I guess they will fill all the three dxz,dyz and dxy orbitals singly and then only start pairing...

[@Honey-yv8fc]

Bhaiya, cu(en)3++ vs Ni(en)3++ which is more stable

[@singh4450]

How will I come to know that in which condition eg filling will take place and in which condition t2g filling will take place? I'm asking because while doing that ques.(regarding distotion) u told that in this eg filling will take place and that t2g filling will take place just by looking at the coordination compund

[@nidhakhan7608]

sir a ques came in my mind u say that whenever the electron is present in the t2g orbital the dynamic distortion takes place n whenever the electron is present in eg orbital the statics distortiin takes place ....Is this mean when z out takes place the statics distortion occur n when z in takes place the dynamic distortion takes place......might b it is a stupid ques bt i have prblm to analyse the ques that why i put out this ques .....

[@rajnirana7234]

Good explanation sir.. Sir, can u plz upload the video on inner and outer sphere mechanism.

[@jefrystairish7924]

Always i come here for this topic..thankyou

[@atikurhassan]

at 23.31 the filling of electron in Z - in case. for d2 case both the electron occupy d xy .why ? i think it is possible that one electron in dxy and one electron in dxz or dyz. according to hunds rule

[@rcchristiantamil7552]

pls tell about what is the function in D9 why it had huge distortion

[@rahulaochar]

Sir, This excellent lecture ...

[@A_Classes]

hello sir.. do you provide subject material....or do you suggest me which coaching is better for GATE chemistry...please respond as soon as possible

[@jhachemistry3443]

sir how we calculate the no of donar electrons of complex ligand given to central metal used in 18,eletron rule..as..(NC me),(As ph2), (N me2)..... please please tell a mathod to calculate this because in exam every year new ligand added.

[@elaanbesivam577]

Thank u sir...ur teaching very useful to me

[@chembasicsbysujitkumar3705]

sir you have told about the atomic term symbols or levels and atomic term but the questions are now in csir from the molecular spectroscopic term symbols and the allowed and non-allowed transitions. so kindly do make a video on this . and please cover the advanced concepts in it as I know to find it using the molecular orbital theory for diatomic molecules in simple cases for O2 and that all but find it difficult to do in complexes mainly organometallics in which the MOT diagram is drawn in it

[@BholaSingh-si4xq]

d2 have Zout (Elongation) jahn teller distortion. please confirm it again bcz 1 electron occupydxy and other occupy dyz so, only - 2/3 remains in Zin.. but in Zout - 4/3.

[@meghagharge9077]

Nice explanation sir. Thank you sir

[@BholaSingh-si4xq]

hello sir.. d8 also show strong distortion in LS complexes.. when both electrons of eg are filled in dx2-y2 orbital.

[@ritukhatri2418]

Sir u said d4 high spin n filled all d four elctrons in dxz and dyz . If it's high spin den dere shuld be 1 elctron in dxy also and 3 elctron in dyz and dxz.??? Plese xplain this sir

[@nargisjafriofficial]

Very nice... Thank you so much

[@iarenubie78]

Hello sir, for a d4 high spin complex, are you referring to the entire metal complex or only high spin in the t2g orbitals. Meaning 3 electrons in the t2g and 1 in the eg OR all 4 in the t2g orbitals? If they are all in they are all in the t2g orbitals, isn't it a low spin complex? Thank you sir

[@eddie01187]

Same qsn frm my side also. d4(HS) should show z-in distortion!

[@digantabala1809]

d4 will show z out .. for s-d mixing ..net jtse is more negative

[@sumanachowdhury473]

Sir, I only cover the topic as u mentioned in ur physical and inorganic strategy. ..is it enough for csir net?

[@sapnabarad1806]

Nice explanation sir... thank you so much ..sir, pls make a video on oragel diagram too..

[@harshitagupta2854]

What is the lowest energy orbital for trigonal prismatic ? Explain it .

[@gollavineetha3482]

For complexes distortion in eg means is it Z-in,n t2g means z-out . please answer

[@letsstart555]

Please tell elongation in dz2 or dx2-y2 ??? .... because this depends upon the last electron where to enter out of these two orbital

[@ritukhatri2418]

Please explain static and dynamic JTD????question cms on dis also

[@harshitagupta6239]

sir please can u make a video on formation of high spin and low spin complexes....because there are certain exceptions in these....

[@reshmapoulose9981]

sir, what about the z in and z out in d4 system???

[@yogeshmanitripathi8452]

very very special thanks to u sr

[@bhawanasaklani4802]

nice explanation sir..thanks a lot... please explain LFT too

[@hassanacademy14]

Nice video.... Thanks

[@tinaprajapati2648]

nice explanation and easý to understand.

[@abhishekraj2194]

sir how we will come to know there is weak or strong jahn teller distortion

[@shubhisingh6422]

Sir, delhi me best Gate chemistry coaching bta sakte h?

[@surajkumarbehera8642]

At 25:59 ap d4 high spin ki baat kar rahe ho per eg orbital me nhi dal rahe ho kuch v electron sare ke sare z in mein rakh de rahe ho....to ye high spin kese ho gaya?

[@aribafatima4354]

Sir in high spin zout case the energy value becomes 1\3.u filled es in wrong way...three es in dzorbitals and one e in dxy.am I ryt ?

[@shubhamkale7474]

Sir please give the list of most imp name reaction and reagents in organic synthesis (selected only not all)

[@adityaraval7331]

Sir please make a video of strategies for entrance exams in chemistry other than TIFR or JAM

[@nareshbekkem7947]

And is it follows 16 electron rule is it correct ???

[@skmursedali3514]

sir,D4 high spin in z-out distortion,why all the electron are filled in dyz,dzx orbital in your lecture 24.14 to 26.2 minutes

[@ajay5405]

Very nice explanation ...

[@abiharizvi5990]

Sir Gate CY crack krne baad kya hogaa....Job milegi ya phir bhi padhna hoga

[@shreyabhattacharya3614]

sir can you explain the non existence of [cu(nh3)6]2+ in aqueous medium?

[@aaishwaryapaul6042]

Dear sir, could you please do a video on LMCT and MLCT?

[@annapurnasaxena68]

sir , high spin d5 is not symmetrically filled as in t2g ,2 orbitals contain two two electrons while one orbital of t2g contains only one electron. plz correct me of I am wrong.

[@shrutimishra4298]

Thnq so much sr

[@amitbvadaverao2339]

At the end of lecture pls solve some previous CSIR question.

[@abhisekbanerjee7057]

Very helpful video for all inorganic aspirants

[@saritalohar9848]

Nice videos sir

[@ritukhatri2418]

Sir why in d4 all the elctron occupy dxz and dyz? In t2g splitting energy is very less so firstly we fill the single elctrons and then we do the pairing.so there should be 3 elctrons in dxz and dyz and 1 elctron in dxy. Is this wrong?

[@ritukhatri2418]

25:07

[@ritukhatri2418]

Gate chemistry 25:07

[@gopalkrishnaniyogi7281]

Sir how can I guess a complex is z-out/z-in complex?

[@sanahaider8831]

Please explain d4 high spin?? How z it z-out?

[@subrahmanyamkorlepara4732]

Sir in d2 in zout case there are two possible cases sir because the second electron can enter in dzx or dyz sir please clarify about that why did u took both are in dxy and energy does not depend on the sign no sir just we will consider only magnitude only know sir please clarify about that sir

[@deepdeep-jp3cn]

Sir in d2 it should be Zout?

[@anshulkapila7572]

Do u have an answer key of tifr all past year papers ?

[@abiolashittu3423]

the d5 low spin is asymmetric and will, therefore, show a janh-teller distortion

[@anamikadas7533]

Yes that's what I was thinking too.. thanks for clearing my doubt

[@abiolashittu3423]

Yea !

[@sassysoma]

Why does jahn teller distortion is not observed at higher temperature?

[@marygeorge7279]

Co(II)-d7 or Cu(II)-d9 which shows greater octahedral distortion? If H2O is the ligand

[@shayalone7893]

I think Cu(II).. be'coz in d9 eg is asymetricaly filled n in d7 it's t2g.

[@chemistryprinciples800]

Very good work

[@kaswar9234]

God plees you sir and thank you very much

[@studysgood5027]

Sirr please tell us something about how to study for NTPC trainee recruitment exam .If you know something about it.. It will be great help if you help in that case...Thanksss

[@jugalchoudhary435]

Very nice sir I do Preparation for iit jam, sir spectroscopy is not clear can help me

[@Leo-xr2et]

Sir, d5 low spin???

[@shraddha1112]

Hello Sir!!it wud be great if u restart daily name rxn...

[@7252chem_man]

📚📚 best ever ..👌

[@souravsahu4727]

Sir, I think filling of d4 high spin complex is wrong. In Z out case you filled it as low Spin. All electrons paired even if empty orbitals were available .Please check 25 min to 25.5 minute of ur lecture

[@soulfulguitar2349]

Sourav Sahu +.yes u r correct..filling of d4 high spin complex is wrong....

[@seetaramkori3745]

I also think d4 high spin should take place like like this.... Z-out. 1dxz 1dyz 1 dxy then 1dxz. So energy = 3(-1/3)+1(2/3)= -1/3 Z-in .1dxy then 1dxz 1dyz then 1dxy So energy=2(-2/3)+2(1/3)=-2/3 -2/3 < -1/3 So compression will take place

[@abhi531995]

Z out will take place

[@RJJasmine]

Gate chemistry sir please check the filling of d4 configuration in zout..

[@nandubhagi3073]

sir the video is useful but let me know how do they ask us in exam.. only in the model of identifying their distortions and stability ?? or else any other model.. and also will they mention the given complex will be high spin or low spin in the given question please give an idea about this sir..

[@hemlatabhatt2865]

really nice video

[@swapnamayeepanda8735]

sir d5 lowspin is assymetry.den why it doesnt undergo distrtn?

[@swapnamayeepanda8735]

thnks fr clarifyng

[@ananyaburagohain9166]

THNKSS, I TOO HAD A DOUBT ON IT...

[@ashmibasicchemistryclasses2226]

Mind blowing sir ji..thank u

[@legend_bhaiya]

sir d 5 low spin no distortion but this is asymmetric

[@spiritualbeing8701]

Actually John teller is takes place in higher amount when eg orbitals unsymmetrically filled right ,but it is quite low when t2g orbitals are unsymmetrically filled .so it is present in d5 low spin but distortion is very low .

[@dipakgonnade961]

Thank you very much
