. Reaction of OsO4 with CO at 125 °C and 75 atm was found to result in a stable compound A with the empirical formula OsC4O4. Compound A was found to contain 3 metal-metal bonds. Reaction of A with excess of sodium metal followed by treatment with H3PO4 was found to result in compound B with the molecular formula OsH2C4O4. Heating of B was found to result in the release of a colourless gas and formation of a compound C with empirical formula OsHC4O4. C on treatment with MeI was found to get converted to D with release of a hydrocarbon gas. D on further treatment with Na/Hg followed by MeI gave E with the empirical formula OsC5H3O4. Compounds A-E obey 18 electron rule and all of them show infrared absorptions in the vicinity of 2000 cm-1. No bridging ligands were also observed. Suggest structures for compounds A-E. Can any one help me!?
Maam, can we calculate the M-M bond order without drawing mo diagram, and just calculating against mathematical rules as used in Metal carbonyl clusters?

Ets me pdhe ho ap
Mam apka organo. Metallic chemistry ka class bohut a66a hai....thanks a lot mam
bond order is 7/2=3.5 the way of teaching was so nice so calculate within seond thanku ma'am
Today I am so happy after watching this video. Thank you, ma'am. Super explanation, I have easily understood.
Kash phle hi mil jata koi aise explain krne wala
You very great teacher for give wonderful lecture to our society.im always thank to you🙏🙏🙏🙏👌👌👏👏👏🌹🌹
Homework to mjhe dena h dt sound so swt ...😍 And we like ok mam ..the way u teach with smile lecture becomes more interesting ..👍👍
Last question
2x=5
Bond order=3.5
Thank you sooo much ma'am
Very good and lucidity explanation
Speechless . Simply " THANKS "
B. O=3.5, thank you ma'am.. . 😍😍
mera bhi same aya
Very NYC explanation mam.this will help us for csir net
your work totally appreciable mam 🙏 thanks alot nd the way you teach us really hattsoffffff
Your Video content is very very good.
Literally ma'am so helpful video thankyou
Answer 3.5 mam,, thank you so much my dear jyothi mam 😘😍👭👍
Thank you so much maam Love you maam😊 amazing the way you taught😊😊😊
Thank you ma'am....
And answer is 3.5 bond order.
Ma'am please explain the concept of labile and inert complexes in terms of dissociative and associative mechanism. Thank you
❤️❤️just love your each and every lectre.Your videos have such a clear explanation.You just put every effort as you can. #Thankyousomuchmam ❤️❤️
Thank you so much mam your videos very helpful
dz² and pz hybridization karke dp hybrid banake sigma bond banate hai na?
Love from Assam 🙏
Bond order is 3.5 Thank you mam
3.5
Thank you ma'am
Can you please explain me how you got Re2 charge in that assignment
2x =5 aaega...therefore just remove 5 electrons from total 14 electrons of Re...9 will left..
1 Radical BO= 3.5 mam 😊 Thank you

Thnku mam😄
Answer 3.5 mam
B.O. =3.5 & hence paramagnetic complex
Nice explain mem
Maam, can we calculate the M-M bond order without drawing mo diagram, and just calculating against mathematical rules as used in Metal carbonyl clusters?
Bond order- 3.5
Mam net exam ki reasoning ke liye konsi book prefer karni chaiye
B.O= 3.5 thank u mam
Can you plz share the different sources that you are referring for a particular topic ... It will be very helpful ...
Mam...ur all videos are very helpful for preparing NET...& I follow every video......... I've a request to you...please kindly make a video on inorganic reaction mechanism...😃& can you give any trick to remeber Orgel Diagram!!..
Mam Pz- orbital to use hi nhi hui....and bonding me d orbital se pehle to p orbital hi use hoti h....plz explain
Bond order is 3.5

Hello ma'am.
Maam please suggest a book which contains Chapterwise questions and solutions(for practice)for iit jam chemistry.
Thank you.
Maam please
Pz orbital overlap nhi karta kya??
Mam why don't you use white board ?
Shukriya mam.....
Thank you mam 😇😇
Bond order of the given compound would be 3.5 mam☺️
Which one example 3.5 bond order?? I can't understand Hindi but all people said like that... Among four example she didn't tell 3.5
@@tamilcitizen2755 last example having +1 charge
Mam plz upload coordination chemistry
But mam only dx2-y2 can form delta bond.dz2 can not form delta bond
What will be the bond order for (Re2Cl8)
Thankss mam
3.5 mam, thank u..
Ma'am what about Pz orbital usko nahi bataya aapne

Thanks mam
Mam Hammett equation par video bnaiye .msc first semester. Organic chemistry
answer for home work question; bond order= 3.5
Thank you 🙂
3.5 mam thanks
Bond order 3.5 aya sahi hai kya diii
22:05 i think it is coloured due to charge transfer spectra🤔🤔🤔
Bonding me 8 electrons and anti bonding me 1 electron so B.O is 3.5
3.5 h ans thankyou
Ma'am mujhe ek confusion h 😥😥😞😞 ma'am wo jo 11:03 pe aapne orbitals likhe usme *Pz* orbital kyu nhi likha ?? Wo v to bcha h na? Ma'am pls btaiye.🙏🏻
Structure mein dekho Re ne total 8 bonds hi banaaye hain...4 with Cl ligands and 4 with Re...so only 8 orbitals will be involved.
pz doesn't participate
@@JChemistry ma'am to Jo *dz²* ne sigma bond bnaya h wo *pz* nhi bna skta tha ??
I mean wo v along the z axis hi h Jese dz² h to..😥
@@JChemistry ma'am pls doubt clear kijiye 🙏🏻🙏🏻🙏🏻
Meri book me ek question h " Name the type of bonding in complex ion Re2Cl8(-2) ."
M kya answer likhu ? Koi answer kro ......Metal - Metal bond?
Quadruple bond as 4 bonds are present between two Re atoms here a special type bonding mode is possible namely delta bond
is this chater for csir net exam ?
Yes
Mam can you suggest writer name for organometallic book
Plz suggest mam writer book name for organometallic
Because it's argent mam
Bond order =3.5 mam
Pz orbital kha contribute krega
Your hairs were dense and long but today they are less dense nd short as compared to earlier 🤔🤔
