Finding Ground State Term Symbol (Very Important) - GATE 2017

The question that came in GATE 2017, very tricky to solve and many people made mistake while solving this question.
Watch video to know exactly how to solve these questions.

[@captainarman3983]

Sir u should make a playlist taking JAM and GATE questions one by one. That would be greatly appreciated

[@AllBoutChemistry]

Nice suggestion, I'll try to follow that... Thank you 😊

[@captainarman3983]

Excellent job sir...we want more like this

[@AllBoutChemistry]

Thank you, I'm making more videos 😊

[@vinispots]

Learned many things from you sir thank you🙏 so much

[@pramilajoshi9712]

That was so helpful..keep up the good work sir..

[@briannagordon1160]

This made it so simple, thanks :)

[@vishesharoraarora4269]

What is d ans if the options are given in mullikens trms . 3T1g or 3T2g ... $ what is in case of configurations d^5 low spin . Bcoz for high spin i get it by orgel diag.

[@vishalroy8741]

Sir had you not taken CF splitting concept the ml value comes to be 6,i.e, 2 electrons in +2 and 2 electrons in +1 orbitals. So should we always use cfse concept in such cases?

[@AllBoutChemistry]

Vishal Roy, this concept is applicable only if you're given with complex in the question

[@vishalroy8741]

All 'Bout Chemistry ok👍 thank you for quick reply 😊

[@AllBoutChemistry]

You're most welcome 😇

[@ucdiaries8064]

you mean the above answer is wrong?

[@AllBoutChemistry]

No answer is correct, check yourself from GATE 2017 answer key

[@krishnapriya.k1052]

How you calculate the l value ..pls reply...sir..

[@dineshkumarsaini2908]

इसका आंसर cr[CN]6 3G nahi hoga kya kyuki t2g orbitals ke liye l value +2 +1 -1 hoti hain dz2 to eg orbital h iske liye l value 0 hoti h dz2 orbital me to strong field lingand ke karan electron jayega hi nahi Please confirm sir in gate 2017 question ground state term symbol dx2 dx2y2 0. -2 dxy dxz dyz +2 +1 -1

[@AllBoutChemistry]

DINESH KUMAR SAINI, Is question me already maine mention kia h ki option ³G nhi hoga qki question me sirf electronic state ya metal cation na de k poora complex dia h, ye ek trick question tha, aur poora complex hone ki wajah se hme ligand k effect ko bhi consider krna hoga... Isliye strong feild ligand hone ki wajah se electronic configuration change hogi aur answer ³H hoga...

[@dineshkumarsaini2908]

All 'Bout Chemistry Strong Field ki vajah se electron dz2 orbital me jayega hi nahi isiliye Sigma L value {+2×2+1+(-1)=4 4 ke liye G hi hota hain Sir dz2 orbital eg orbital hone ke karan dz2 me electron nahi jaayega Please confirm Sir please

[@AllBoutChemistry]

DINESH KUMAR SAINI, I think you're confused in ml values of d-orbitals. The ml values are -2, -1, 0, 1, 2 for dx²-y², dz², dxy, dxz, dyz respectively. Now I think it'll be clear yo you...

[@dineshkumarsaini2908]

All 'Bout Chemistry OK Sir thanks I confirmed Kuch book me dz2 ki ml value 0 de rakhi hain Yeh ml values jo apne batai hain wo hi fix h na d orbitals ke liye dz2 orbital ki ml value kuch book me 0 de rakhi hain likely that jaise pz orbital ki ml value 0 hoti h

[@AllBoutChemistry]

DINESH KUMAR SAINI, Follow standard books... JD Lee me dekho, Huhyee me, Shivers and Atkins me... Ye sb standard books h... Inke data reliable hote h

[@Sonalinsenapati]

Sir it is an example d3 term symbol??

[@Sushanth98]

d4 low spin complex

[@nba9604]

Sir is there video for mulliken symbol?

[@pksir888]

Sir esse hi video ...regular dal digiye

[@nileshkokate6816]

Sir . What about the -4charge given in complex

[@surbhikumari9636]

Sir jha aapne n+1 likha h wha pe 2S+1 mtlb spin multiplicity likhte h na

[@surbhikumari9636]

Plz reply

[@AllBoutChemistry]

Haan baat ek hi Hai qki spin of electron is 1/2 to chahe n+1 kr lo jaha n means number of unpaired electrons honge.

[@parthmistry4799]

Vry nice explantion sir ... Thank you

[@santokhsingh1696]

Very nice😎😍🤩

[@SantanuDas-wq1qx]

Sir what will the value of "J" In that case

[@jordan203]

nice .. really it is very conceptual nd important

[@charupiplani2624]

If there is ground state term symbol asked den also is same answer??? If J value is not given in answer

[@AllBoutChemistry]

IN this question complex is given thats why we have taken effect of ligands in it. if it is simple ion then we dont have to worry about the splitting and alll..

[@ishitadas6218]

Thank you for clear explanation.

[@prashantchaudhary9979]

Ty sir .....and what is the term symbol of V3+ ion .....can u plzz tell me

[@noorfathima7530]

Hey they asked about the ground state term not the first excited state term..for d4 system pentate D is a ground state term..triplet H is first excited term

[@AllBoutChemistry]

Noor Fathima, check out GATE 2017 Question Paper and Answer Key on GATE Official website. This is an exceptional case asked in exam and it should be done like this.

[@noorfathima7530]

@@AllBoutChemistry but how it is an exceptional case?chromium is in +2 state..no one files the objection at dat time for this answer i guess...

[@AllBoutChemistry]

No, it's not like that, Cr+2 with strong feild ligand is given, now whenever you have question like this where you're given with complex then your ligand will also play role in deciding term symbol. That's why the effect of CN ligand is taken over here. For reference you can see James E Huhyee, or Meissler and Tarr there many examples like this are given.

[@rajput9s764]

Thankyou so much sir😊😊😊

[@jyotisaini9534]

thank you for the solution

[@supriyabodake4366]

good explination sir thanks.....

[@vanitak4739]

Very well explained sir thnku so much

[@Marthand777]

Sir What will sigma ml value if it were tetrahedral arrangement

[@AllBoutChemistry]

The filling of electron would be different for tetrahedral arrangement as T2 will go up and E will come down, Now it depends on question that what will be value of sigma ml there.

[@Marthand777]

Sir how to solve multi step reaction constant

[@AllBoutChemistry]

ok sure

[@ucdiaries8064]

is this wrong answer?.someone commented like that know

[@AllBoutChemistry]

No answer is 100% correct

[@krish65950]

Thank u Bro for neat explanation

[@hiteshwankhade7846]

sir ²s+1L. ?????

[@AllBoutChemistry]

sorry.. i didn't get you...???

[@sushmitamondal962]

Thank U So Much....

[@sijimanoharan6554]

Thank you so much

[@sunil..8547]

Thank u so much sir🙏

[@susmiraja]

Thank you sir

[@mdaftabalam8845]

The ground state for[co(H2o) 6]+2 solve sir please🙏

[@ANJALISHARMA-ju5dx]

If it's not for complex dn d5 is correct

[@OpeDJ]

Thanks a lot Sir

[@chemicalsciencebyhiramanud8413]

Thanks sir

[@AllBoutChemistry]

you're welcome :)

[@vishnusankar7189]

Great explanation... please give quantum mechanics lectures

[@AllBoutChemistry]

Thank you... I'll sure make videos on Quantum soon.. :)

[@ankankumarghosh8769]

Thanks 😊 sir

[@mrbhilavekar]

Ok thank you sir

[@wajidatabassum4448]

👌👌👌👌

[@poojakanwar8748]

Thanks

[@MsSris2011]

Thank u

[@deepjyotibora6407]

Its answer should be B

[@learnchemistryineasyway2049]

3F

[@kabilans1212]

great sir

[@birdfree6439]

But electron shld get singly occupied first....

[@bhagavanchowdary2303]

But in the case strong field ligand is there , hence in the octahedral splittings t2g electrons first fill

[@sobiakhan709]

Rly btfl expltn

[@AllBoutChemistry]

thank you

[@pg-trb-chemneetcsirchem5282]

Hand's up to you sir

[@alishakakkar6096]

L value comes out to be 6 I think all the options r inorrect

[@himanshig5672]

Thank you sir
