I had a hard time following you, but it clicked when I concentrated on what you say. I would like to thank you, and I appreciate all the efforts to make this video. This video is informative and effective. Keep up. A new microphone is needed. :)
Thanku so much sir for every lectures ....I hv doubt in video tht d4 low spin complex you discussed for z in or out why do I fill dxy in z out it is low spin so I should be paired I think
Sir jahn tellor distortion vali video me z out me d4 ki filling shi nhi h. Sare electrons dxz or dyz me aane chahiye please watch it again and reply me
Sir, at 33:09 you were discussing d4 low spin and since in case of low spin, electrons are paired up in the lower energy levels before going to fill the electrons in higher energy levels. So, shouldn't dxz and dyz orbitals be filled up completely before moving ahead to fill the dxy orbitals? Or since all the orbitals in t2g level are degenerate, we have to follow the hund's rule while filling up the electrons?
Yes in case of d4 low spin but t2g orbital is split so dxz, dyz and dxy all are the orbitals of t2g so must be filled wd electrons... Delta O is overall not only t2g.
Sir at 38:57 , when you were discussing unstability of chelating complexes mentioned that [Cu(en)3]2+ will undergo Jahn Teller distortion and this will cause an elongation in the axial bonds. So my question is - how did you know this will undergo Z-out splitting? I mean, we can't predict it. So can we take any of the elongation - axial or equatorial, since both of them will finally make the complex unstable for sure?
Yes definitely, since we can't predict which elongation or compression it will undergo, but this is sure that there will be changes in bond length along axial and equitorial positions, so there will be unstability. But yes you're correct that elongation and compression can't be predicted.
Nice video for better understanding. but i have a confusion that... for d4 (L.S) ( Z-out) all the four electrons goes to the d(xz) and d(yz). I think the 4th electron will not go to the d(xy) orbital
thank you for the video! However can you please explain on 33:05 in the z out case, you put electron on the 1 electron in dxy, 1 electron in dxz, 2 electrons in the dyz? because as I understand as a low spin cmpd, I get 2 electrons in the dxz and 2 electrons in the dyz (the 2 lowest orbitals in the energy diagram).
9:20. Don't you think d3 is asymmetry for both HS and LS? Because I think the more unpaired electron will be asymmetric. And in both HS and LS, they have the same number of unpaired electrons.
Sir as u mentioned in this video that co +3 ie d6 system with cl shows high spin ....but co + 3 oxidation state shows always low spin......only with flourine it will show low spin.. So that complex is sym and it wont show J T ...if m not wrong
In determining strong and weak distortions, how will it occur for d1 and d5(low spin) ??? What will be the answer sir. Will both show low distortion or will there be any change in my statement??
Question at 36.06 should have (b) option also as the answer. Term symbol for d5 is S and in case of S the ground term is A1g. If i am wrong please correct me.
Your argument makes sense, Himani. 1 unpaired e- in t2g set has got only one way of occupancy, i.e , the degeneracy here is 1C1. Hence, the ground-state term symbol A1g is a valid option.
Sir, if an octahedral complex having all same ligands undergoes JT distortion, will resultant tetragonal complex would have inversion centre and accounts no dd transition. Plz clarify. Thank you.
Pls add related topic videos link on ur discription box that more comfort for search the topic and pls take class on energetic mode. Otherwise ur class is too good.
Sir please answer this question. jahn- teller effect is in the field of. (a) Nuclear physics (b) Nuclear chemistry (c) vibronic interaction (d) kinetic theory of gases
Sir in d4(L.s).. (How to find Zin/zout) The 4es are frst filled in low level I mean pairing tha electron, but u tell 3rd electron will go higher and then the 4th electron put in a low level ,y??? Pls reply sir
You told in this video...if there is unsymmetrically eg orbital...it will be z out case...but here in this book (solutions of net previous year question paper);there is two options..1) three long and two short 2)two long and three short. But in the book ..1 st option is the answer ..Sir I am confused..plz help
Write out mechanism for the inner-sphere electron transfer reaction between [Co(NH3)5SCN]2+ and [Cr(H2O)6] 2+ that produces the pentaaquo-Nthiocyanatochromium(III) cation as one of its products.
