Mam why in ques 2 where ∆H was asked....why we can't use the concept of the amount of electron density,as Ni has greater electron density(d8) ,so it's cp complex has greater back bonding and consequently greater ∆H
Good Morning mam!!! Condition of isolobal 1) Valence es same 2 ) Co ordination no. Same QUESTION NO. 3 CH4 = 8 valence electrons Ryt. CH4 is isolobal to Cr(CO)6 only because Cr(CO)6 has (18 -10 = 8 valence electrons) and has Same coordination no. = 6 (tr metal) which matches with Cordinatin no. 4 of CH4 ( main gp ) . Inshort I want to how CH3- is isolobal to Cr(CO)6 ?? because criteria of valence electrons is satisfied here but not the coordination no. Criteria . PLEASE REPLY
Firts view I was waiting for you... Mam 😍😍checked 2 times also.... Mam 1 more request also to you please after the exam of gate please upload the lectures on the Nanochemistry... I don't get the material . That actually clear the concepts please.....
I always watch each and every add without skipping while playing the video 😅.....Ma'am you always think for our benefits ...so we should have to do some benefits for you..😁 And this series is really helpful ma'am 💚🙏
Cr(iPr)4 will not carry beta elimination, it is fact in Crabtree book as the beta H even though avaibable but other 3 groups will provide hinderedness when Cr approches. As in question 5 no temp is mentioned so ans should be 2 species.
Hello Mam! In question 3 you have mentioned that methane is isolobal with both CH3- and and the chromium complex. For isolobality not only similar no. Of electrons but orbital symmetry is also important for the 2 species compared which is not the case with CH3- as it has one vertex less than the parent polyhedron unlike CH4 where all the vertices of a tetrahedron are occupied. So I think CH4 is only isolobal with the Cr complex and not with CH3-. Your thoughts please??
Isn't the answer of the 2nd question coming straight from bond order calculation of M(cp)2 type compounds. With more electrons than d6 as M+2 state the bond order decreases due to occupancy in antibonding mo. The same answer comes from this logic.
Maam.. In last question, The isopropyl Cr complex is unusual presumably their sterric bulk prevent the beta -CH bond from reaching the metal. This compound seems to be sterrically saturated. So beta hydride elimination don't occur and can be synthesis. Is it?
@@JChemistry Mam Aapka reply is accomplishment for us.... On a lighter note GATE exam and good job for overall family is every aspirant final crush ... :)
Great work didi!! Keep going with this for us to keep going with chemistry.❤❤JAM ke questions bhi zyaada karvaayiye didi. 2 hafte hi bache hai. Humble request hai aap ke liye.
Ma'am 2nd qstn if we consider the electron density , I,e highest in Ni then Co then Fe . Uss hisab se toh reverse order ho jayega. Ma'am one more thing , kya ye hum Metallocene ki M.O diagram se bol skte hai ? Jaise ki for Fe2+ all e reside in bonding orbital so for that ∆H value high , but for CO2+ one e- in antibonding and for Ni2+ 2e in eg* ?? Please reply
In the 4th question How can we ignore the +1 O.S of Ir in the last option? With +1 O.S it won't under go backbonding properly so has a good chance of having dihydrogen ligand. And can CN be factor to decide also?
Mam, I am preparing this time for gate and watching your videos. In question 4 NAT type . Can Mo occupy 7 ligands around it because stable Coordination no. will be 6 right?
Mam in question 2..can't we comapre metals by their electron densities...like...fe2+( d6), Co2+(d7) and Ni2+(d8) ...so Ni should show more Backbonding..?
Maam in last question there is 4 bulky ligand with Cr. Bulkyness of the complex decreases the beta H elimination.is there beta H elimination possible???
Mam . NAT -4 Option A me jab ham hydrogen sigma bond k through electron de rhe han .to ye 1e- donar hoga ..overall molecule me 17 e-s hojayenge ..jo ki unstable ha... Kya ye hydrogen ase rhna chahegi?

You have selected very very interesting questions to discuss.
Wow... All question is ...Conceptual and clear more than quarry... Thank you ma'am...
Good Morning mam!!!
Condition of isolobal
1) Valence es same
2 ) Co ordination no. Same
QUESTION NO. 3
CH4 = 8 valence electrons Ryt.
CH4 is isolobal to Cr(CO)6 only because Cr(CO)6 has (18 -10 = 8 valence electrons) and has Same coordination no. = 6 (tr metal) which matches with Cordinatin no. 4 of CH4 ( main gp ) .
Inshort I want to how
CH3- is isolobal to Cr(CO)6 ??
because criteria of valence electrons is satisfied here but not the coordination no. Criteria .

Have been waiting for this ma'am! This series is going so well👍😄
Yes, I got li'l late today 😅
@@JChemistry Doesn't matter ma'am. Day has been started with your video, it's definitely going to go well. 😊
That's the spirit :)
Thanku mam for this videos
Your collection of questions are very helpful unique and fine mam. That's why i called you a teacher of next gen level.
Thank you 😊
Question 4 Explain just wow 😍

for questions no 2)
According to 18 electron rule Ni complex will undergoes dissociation while other 2 associative Then how it dissociated

Thank you mam to help us in this vital time of our preparation.
Was very very much helpful,,👍👍👍
Most awaited session... really helped me a lot
Thank u so much ma'am
Glad to know that :)
Ma'am gate newly added topics confusing me ... whether should I read it now or not😢😢
You should focus more on revising whatever you've studied till now.
Okay ma'am
Thankyou ma'am for the series ma'am. Great help!
Maam.. In last question, The isopropyl Cr complex is unusual presumably their sterric bulk prevent the beta -CH bond from reaching the metal. This compound seems to be sterrically saturated. So beta hydride elimination don't occur and can be synthesis. Is it?
For question 2 ,explanation can be given by the number of valence electrons (18,19,20 electrons).
We wait for this series more than Kapil Sharma show or GOT or a reply from the crush ....
Hahaha
Well that's the biggest compliment this series has got till now.
Bas reply from crush waale case pe doubt hai mujhe 😅
@@JChemistry Mam Aapka reply is accomplishment for us.... On a lighter note GATE exam and good job for overall family is every aspirant final crush ... :)
So thoughtful of you.

Was waitng till 12am yesterday bt my day strted with such amazing questions.thnk u ma'am
3rd question is my favorite question of this series thank you mam..
Great work didi!! Keep going with this for us to keep going with chemistry.❤❤JAM ke questions bhi zyaada karvaayiye didi. 2 hafte hi bache hai. Humble request hai aap ke liye.
Thank you fir this video Mam 🤗🤗🙏🙏🙏❤️❤️
Mam I couldn't not understand example 2 , we could also use 18 electron rule and then the answer will come reverse of your argument....
Thank you so much mam for continues series
Mam p(me)3 & p(et)3 to sigma star acceptors hote hai......please confirm mam, aap ne donor btaya hai
Thank you so much mam..A big Thanks to you♥️
Ma'am 2nd qstn if we consider the electron density , I,e highest in Ni then Co then Fe . Uss hisab se toh reverse order ho jayega.
Ma'am one more thing , kya ye hum Metallocene ki M.O diagram se bol skte hai ? Jaise ki for Fe2+ all e reside in bonding orbital so for that ∆H value high , but for CO2+ one e- in antibonding and for Ni2+ 2e in eg* ??
Please reply
Yes mam....agr hm metallocene ki MO diagram se solve kre tb to reverse order hoga
Maine socha ki main sabse first viewer hu..ake cmmnt mein dekha to 3 cmmnts a chuke hai..koi nai main to mam ki vdo se hi khush hu
Hahaha
In the 4th question
How can we ignore the +1 O.S of Ir in the last option?
With +1 O.S it won't under go backbonding properly so has a good chance of having dihydrogen ligand.
And can CN be factor to decide also?
But down the group BB increases.
....
Mam, I am preparing this time for gate and watching your videos. In question 4 NAT type . Can Mo occupy 7 ligands around it because stable Coordination no. will be 6 right?
In question 4 , Pme3 is a sigma donor pi accepot ligand like CO. The way you explained is not enough to justify.
Mam ques.2 mein Ni wale complex mein 18e- hai to usme sabse zyada backbonding kyu nhi hogi???
In cr(IPR)4 no Beta elimi. Because steric hindrance
Mam in question 2..can't we comapre metals by their electron densities...like...fe2+( d6), Co2+(d7) and Ni2+(d8) ...so Ni should show more Backbonding..?
Thank you so much maim..🙏🙏
In the 1st qs in option b if hydrogen is more deshield zone then it will come to the less negative toh B= 1 hoga. Am I right??
Mam question 2 me hmne d electrons ka concept kyu nhi lgaya
Thank you mam for your support 😊😊😊
Only for gate qualified .......koi major topics bta do mam
Great..waiting for it

Ma'am, NAT Q4. mein agar H2 dihydrogen ki tarah nhi hai phir to coordination no 7 ho jayega to phir steric crowding se complex destabilize nhi hoga ?
Mam Cr(i-pr) wale complex mai beta elemination nahi hoga
And 5 memberd ring wale mai bi difficult h angle 100° k aspas hona chahiye
Ma'am what about gate newly added topics?
Ma'am CH3- is isoelectronic with CH4.. But does it isolobal with that?? Because CH3- has one vacant site na.. Please reply ma'am...
Maam in last question there is 4 bulky ligand with Cr. Bulkyness of the complex decreases the beta H elimination.is there beta H elimination possible???
Mam I am preparing for pcs exams and I have taken chemistry as my optional sub..so I request you to make some vids for pcs..

Mam .
NAT -4
Option A me jab ham hydrogen sigma bond k through electron de rhe han .to ye 1e- donar hoga ..overall molecule me 17 e-s hojayenge ..jo ki unstable ha...
Kya ye hydrogen ase rhna chahegi?
In both ways 2H can donate two electrons if you calculate through neutral method
