1) D
2) C || 2 Cr+3 cation so there is CFSE = 2*12 = 24 Dq
normal
Thanks
Thanku
Thank you!
1st Q : ans. is option (d) Fe3O4 and NiFe2O4 are inverse spinels.
2nd Q : ans. is option (c) normal spinel with total CFSE -24 Dq.
Yes
Very good explanation sir...
I understood.....I'm a lecturer....
U r my inspiration to take graduation clses ....
You teaching style is very good, you explain all the things releted to topic
Grateful to you master. 🙏
May Allaah bless you immensely... I used to be so confused on this concept and MashaAllaah you explained it so brilliantly...

Thank you sir
According to author Ajay Kumar, MgFe2O4 is inverse Spinel
Sir, pls make video on water exchange and isomerism
Sir, plz do the second question
Sir pls make a video on angular overlap model
Sir plz explain 2nd question which you have asked
1-d and 2nd-c
Devudu 🙏

Thank you so much sir I don't have any idea about spinel you have to explain clearly in spinel one again thank you so much sir
Glad to know that 😊

Sir in Gate 2012 one question was asking from cfse i.e
Co3O4,Fe3O4,Mn3O4 which one is the inverse spinel structure...
Fe3O4 is inverse..Co3O4 and Mn3O4 are normal...
Sir ,what about Co3O4..as this rule it should be inverse but actually it is normal
Sir second last ka answer (d) aayega and for last normal spinel and -24 Dq aayega.
What is the condition for mixed spinels?
11.18 Third point d5 is there Sir .Can u clarify that.
1.d & 2.c

🙏👌🙌
Plzzz make videos on isolable analogy

It's already there, plz check
Can you please explain co3co4
How to find total cfse should we add both M+2&M+3 cfse together
Yes
1 ) d, 2)c

1) d
2)c
How can scientists consider molecular term symbols like capital sigma phi Del from quantum chemistry????... Please reply
th-cam.com/video/K8BWuhSNJyg/w-d-xo.html
Watch this video I've explained it here
Tq... Sir... I saw... But what is the link between these symbols and molecular term symbols???... Please reply
Ans 1) d inverse inverse
Ans 2) c normal and -24dq for 2 cr+3
2 ka ans how did u calculated can u plz miss shalini....
For 1cr III youll get -12 but here 2 cr are there so 12 *2 = 24
Oo....oh ya we have to multiply it....thank u so much miss.....r u preparing fr csir?
Among the compound fe3o4
1)d
2)d
Sir, is this topic important for csir net or not?
3:17 pr A+ tetrahedral voids m hi jata hai
In last question the total cfsc is -12 Delta. But in option it is not there ,so suggest the correct answer.
2 Ions of Cr3+ is here so it becomes 2*12=24Dq
1 answer d. Second one is normal but cfse is confuse sir
Qn1 option d
Qn2 option c
NiAl2O4 में Ni +2 ka hybridisation kya आयेगा???
2-c
Question 1...answer d...Question 2...answer c
how can you compare Fe3+ and Zn2+ size along the period. As size of 3+ is always smaller than 2+.
I also have doubt..
Which have more d electron and compare electronegativity from left to right and than analysis size
Or u can think in this way (which i found helpful in solving such questions) ..
Higher O.S will have more C.N.
Here ... Fe = +3 (so it can be in octahedral)
Zn2+ can be in tetrahedral.
Therefore :- Normal spinel.
High spin lenge ya low spin ????
Sir why Hg+2 ion not formed spinels.?????
Calculate % of occupancy of Ni+2 ion Oh void in spinel NiAl2O4 having λ=0.4?
How to solve such questions?
Is the answer 10%?

what's the mixed spinel of MgAl2O4 ?
Normal spinel
What about Co3O4?
