Sir plz post the part 2 of conformations of cyclohexane .... You posted part 1 , one month ago which was very very helpful and a total blessing.... We can't wait for part 2 ... NET exams are near ... Help us sir
Sir... When vaska complex reacts with cl2 to form Trans product through Oxidative addition... Then how CO frequency of pdt is grter than that of reactant..... Csir June 2012... 34...
in product metal Ir is present in higher oxidation state [+3] ,less back bonding to pi* orbital of CO .....then C triple bond O bond is strong ....CO.frequency will bemore
Hey... As ligand field strength increase spin cross over takes place at certain delta value... And. After this crossing. .1A1g becomes ground state then(in low spin region) two transition 1A1g to 1T1g and 1A1g to 1T2g takes place....
Hey.... In low spin d6.. term symbol is... 1I and 1A1g is it's ground state term whereas 1T1g and 1T2g are its excited term (as...3T1g, 3T2g and 3A2g are ground and excited terms of 3F)...hope you understand
Sir, chapter wise numericals book Jo ki net level ki hoo.jisme all Chemistry chapter and full spectroscopy ka numericals hoo.sir, book ka naam suggest krayia.pls.
sir u have said that dynamic distortion takes place at low tempt and there occur the quick exchange btw z out n z in so g parallel n g perpendicular become equal so we get only one g value bt here u say that at low tempt we get two values of g ...explain sir
Hi ....sir how to approach 2016 december booklet A,question no -22.My explanation is -nitro gr has highest trans effect among them so nitro gr will produce high amount of trans isomer by removing chlorine gr.thus results lesser amt cis pdt.Tell me is this explanation is correct or not?
Sir...Is there any book available in market which contain chapter wise question with correct answer ...for JAM...if available plz tell me it's publication / book name/ author...
Please once check out the question that came in 2015 December.set-B. tebbe olefination followed by intra molecular diels alder reaction but I can't understand stereochemistry of the product.please answer. For this question.
Krishnendu Chandra... This complex.... At low tempr becomes.... Low spin d6...ie zero mag moment... Whereas at high tempr it is high spin...n=4 means 4.9BM mag moment.... (spin cross over takes place at 81K for this complex) and you can find cfse value easily
Yeah....This is jst becoz high spin form of a complex occupies Larger volume than that of low spin complex (eg orbitals are effectively filled in high spin) which is favoured by HIGH TEMPERATURE and LOW PRESSURE... And vice versa ie... Low spin favoured by high pressure and low temperature...
Your contents are of great help.

We can't wait for part 2 ... NET exams are near ... Help us sir
baut badiya h sir... 😊😊😉
Sir.. Kitne temp.. tk low temp consider karenge.. & then high
👍well explained all parts of esr. Thnku sir😍
Very nice explanation sir
how to know the value of g parellel and perpendicular?
pls tel me
How to explain the value of 7/2 for the quantum number of nuclear spin V (Vanadium) in EPR? Why not other value as 5/2, 3/2, etc?
Sir... When vaska complex reacts with cl2 to form Trans product through Oxidative addition... Then how CO frequency of pdt is grter than that of reactant.....
Csir June 2012... 34...
in product metal Ir is present in higher oxidation state [+3] ,less back bonding to pi* orbital of CO .....then C triple bond O bond is strong ....CO.frequency will bemore
ms... Ji thank you
In case Cu2+ , have a possibility of z-in/z-out...... So may be possibility of double line as like the case this vanadium acac complex?
Sir what is oxidation number of V in this complex
why not protons are considered while calculation of splitting since they too are present??
U dont make third part of epr spectroscopy??
Sir here hydrogen atoms doesn't take part in splitting?
Hi...sir pls tell me why low spin Co (3+) give two transitions ....as it is described in Hueey inorganic chemistry ,page no .472
Hey... As ligand field strength increase spin cross over takes place at certain delta value... And. After this crossing. .1A1g becomes ground state then(in low spin region) two transition 1A1g to 1T1g and 1A1g to 1T2g takes place....
How T1g and T2g state comes. ..pls explain
Hey.... In low spin d6.. term symbol is... 1I and 1A1g is it's ground state term whereas 1T1g and 1T2g are its excited term (as...3T1g, 3T2g and 3A2g are ground and excited terms of 3F)...hope you understand
Yea...i got it.2016 june question no-71...redarding electronic transition....if u able to solve then answer it
Krishnendu Chandra.... Booklet code A?
Sir here is no jtd then how we calculate that g parallel and g perpendicular
Sir mass spectroscopy ki videos ni mil ri sirf ek hi video h kya
hello sir i how to solve csir 2017, question no 95(booklet a), and doubt about question no 89, regarding formation of 2nd product
Sir, chapter wise numericals book Jo ki net level ki hoo.jisme all Chemistry chapter and full spectroscopy ka numericals hoo.sir, book ka naam suggest krayia.pls.
V(2+) there is 3 unpaired electron so why not 8*3=24 ?
Jayanta Dey but why are protons not considered in this structure only vanadium?
Vanadium is in +4 state
sir u have said that dynamic distortion takes place at low tempt and there occur the quick exchange btw z out n z in so g parallel n g perpendicular become equal so we get only one g value bt here u say that at low tempt we get two values of g ...explain sir
What are the criteria to show fluxonality in molecule.. Plz make vedio on this topic.
Sir hme kaise pta chalega ki temp low h means 77 k temp. Is lower for this complex
Hi ....sir how to approach 2016 december booklet A,question no -22.My explanation is -nitro gr has highest trans effect among them so nitro gr will produce high amount of trans isomer by removing chlorine gr.thus results lesser amt cis pdt.Tell me is this explanation is correct or not?
Thanks bro for your valuable help.
sir mere se structure determination spectroscopy ke q solve ni ho rhe h .
sir plz meri es problem ka solutio bto
thanks man
pls suggest NMR book for inorganic molecules
Aadil
k
Sir, make a lecture on how to determine molecular term symbols.
Sir...Is there any book available in market which contain chapter wise question with correct answer ...for JAM...if available plz tell me it's publication / book name/ author...
Okay...sir
Plz sir make a video on question number 132 from Dec 2016 paper of A series
thanks sir , plz upload video on molecular term symbol
Unacademy pe dekhi
sir plz make the video on ..how to see raman active molecule...very confusing
Sir plz say about the name important organic reactions For gate 2019
Please upload a video on palladium catalysed all coupling reaction's
Gate chemistry.... Sir we really waiting for this topic
Thank you sir.
Please once check out the question that came in 2015 December.set-B. tebbe olefination followed by intra molecular diels alder reaction but I can't understand stereochemistry of the product.please answer. For this question.
Sir plz solve more question..
Plz cover all the topics in EPR
Gate chemistry thanq Sir
Sir I requested to solve a problem QN.109,june-16(set-c).
Thank you so much sir
Again I request to solve a problem QN. 126 Dec, 16 (set A) sir.
I solve this sir.
thanks a lot sir
thnk u sir....
thank u
but this video is also not clearly visible. . although voice is enough but still
+Gate chemistry thanks...will switch to another network
My another request to solve 2015 june ,booklet -A,question no -92 related to spin crossover equilibrium
Krishnendu Chandra... This complex.... At low tempr becomes.... Low spin d6...ie zero mag moment... Whereas at high tempr it is high spin...n=4 means 4.9BM mag moment....
(spin cross over takes place at 81K for this complex) and you can find cfse value easily
Yea...i was confused that at low and high temperature which spin confirmation will be preferred. ...thanks a lot
Krishnendu Chandra.... Hey... But I jst made a mistake... The spin cross over takes place at 171K
Hi...can u explain why at low temperature low spin state is preferred and high temperature shows high spin state.....thank u
Yeah....This is jst becoz high spin form of a complex occupies Larger volume than that of low spin complex (eg orbitals are effectively filled in high spin) which is favoured by HIGH TEMPERATURE and LOW PRESSURE...
And vice versa
ie... Low spin favoured by high pressure and low temperature...
