Thank u so much mam it really helped me in my exam the same concept came ❤❤

[@kashminaakhtar4405]

Thanku thanku thanku so much,,, itna kom time me app ne pura matter bohot a66ese explain kiya😊😊😊👍👍👍

[@madhunaidu2541]

U r really a great lecturer mam....thank you mam....

[@ankitatandi365]

Thank u so much ma'am. It's very good and clear my concept

[@priyasardar7682]

thank u mam ... plz keep on uploading such videos .... students like me needs u .... i cant b able to go tuition for #net exam

[@abhishekpednekar8468]

Good work mam keep uploading we need more videos.

[@sadiasadia5924]

To much helpful

[@vidyabisht2986]

thaks ma'am........this is vry hlpful....

[@hemlatabhatt2865]

I think in order To(CO)6 should be in second position in decreasing order ,,,please ans

[@shumailzafar9146]

Ti complex where are the 2 anion?
Also order is right. But negative charge on Vanadium will effect frequency ?
Because Ti has only one electron so it should have atleast pair of electron to do back bonding. So therefore it's of lower order

[@shumailzafar9146]

I just concluded that
Ti (CO)6 has lower stretching frequently because it possess no back bonding.
Because of d1 system
As 6×2 = 12 Carbonyl electron
2s2 d1 = 3 electron /18
3+12 e/18
15/18
Ti complex do not follow the 18 rule how it will form because it is unstable

[@jetlinkarkha9659]

I think mam forgot something it may be 2- electron present.so -ve charge increase pi backbonding so lower vibrational stretching frequency...

[@renz9168]

Actually its -2 charged....i guessed she missed it

[@renz9168]

@@PriyankaJainchemistry Maam you could pin a comment stating that so no one get confused 😊

[@harini_prabhu5437]

​@@renz9168thank you 🎉

[@venkatakrishnareddynareddu7906]

Nice lecture madam

[@swathij4084]

How to find the nature of the back bonding by ligands is it by spectrochemical series mam ??

[@Natharti_sanatani]

❤️❤️❤️❤️❤️😇🙏Thanks a lot dear Mam

[@shumailzafar9146]

Just was helpful from start

[@kanwalwaheed6915]

Thank u mam

[@renz9168]

Tysm...last qn there is a error as it is [Ti(CO)6]^(-2)

[@coronarelifetigerforceik3088]

Very good

[@dishabhattacharya7365]

How [Cp(CO)2Fe]- has d-8 configuration?

[@ashish3212]

thank you 🤗🤗🤗 mam

[@prabhchemistrytips803]

👌👌👌

[@narotamkumawat5865]

Which have more stretching frequency between co and co+

[@1233681]

can u tell me how fe is d8 and d6
in feco5 and feco4br resp.

[@simonegabellini6382]

she used the 18 electrons rule

[@md.akibhasan5633]

thanks

[@laxmibaibhavikatti1395]

thank you mam

[@sharmisthamahato404]

plz make nitrosyl compounds..especially bent linear nitrosyl compounds

[@kishnamandal6798]

also about carbonic anhydrase

[@tufeelmir4753]

thAnkz

[@priyankarmajumder9678]

can u pls add a lecture on the strechimg frequency of nitrosyl ligands@priyanka jain mam

[@kaveriagrawal9127]

mam ur way of explaination is quite gd but l didn't get d concept of last problem plz explain ........

[@kaveriagrawal9127]

ok got it , thnx :)

[@poojasutharsuthar1143]

Last Ti complex is neutral. Then why it doesn't exist in 2nd position

[@madhuarora1697]

Why bridging have less. Vibrational frequency than terminal

[@maheshtumkurmaheshkp3903]

madhu arora, note that the electron count cant tell us about the existence or absence of the bridging carbonyls. This has to found from the experiment

[@rockeykumar8552]

mam Tico6 will be on 2nd postion here its having less d electrons and poor back bonding here ..i tnk [TI(CO)6]-2 HAVE less but here u wrote TICO6

[@kishnamandal6798]

about Metal to ligand & ligand to metal charge transforme

[@nituyadav120]

plz ans why pme3 better electron donor than pph3 as a ligand

[@sidyad5319]

Methyl is e- donating so it inc. e- density

[@muhammadkk4083]

here in last example all are in d6 configuration

[@nausadali9943]

Howz u define electronic configuration......🤔🤔🤔

[@incredibleminds3322]

Last example plzzz explain configuration

[@krishnaraoragavendran7592]

Theres confusion wrt Ti(CO)6

[@PriyankaJainchemistry]

Actually it is Ti(CO)6 -
I have corrected it in comment box

[@kishnamandal6798]

mam send video about carbonic anhydrase

[@gopalkrishnaniyogi7281]

OK mam.

[@krishanmudoi2572]

I have a doubt on Ti(co)6

[@jetlinkarkha9659]

See my reply on shemuli zafar.correct me if I m wrong.it will help me..

[@hemlatabhatt2865]

and also have d6 while To has d4

[@jagadeeshmanda2497]

Madam in last problem Ti complex has less electron density means lower backbonding so higher frequency na but u give lower frequency plz explain

[@jagadeeshmanda2497]

Priyanka Jain how it will observed mam

[@jagadeeshmanda2497]

Now accepted madam

[@jagadeeshmanda2497]

Plz give reference book for this concept madam

[@satyabratbhattacharjee9772]

Me Jee aspirant among gate aspirants xd

[@kishnamandal6798]

mam I am preparing iit jam 2018 plz send

[@hemlatabhatt2865]

sorry all

[@dr.d.srividya4911]

Just reading give reason

[@kishnamandal6798]

mam send quickly I am preparing iit jam 2018

[@rushillakdawala4402]

Result?
