Sir your quantum is fabulous
Thanks :)
Thank you, sir, for these types of important videos. Yes, you are true that many of the bio students suffer in thermodynamics and quantum, even I am one of the sufferer but I never feel shy and I always take help of my friends. It would be grateful if you will upload videos on some basic concepts of maths whenever you get the time. Kindly, also mention the topic in which those concepts are used. for eg, Trigonometry is used in solving questions of quantum chemistry.
+suman lata yes I'll try to make vedio soon on basic mathematics
Thank You so much, Sir.
best way of solving Q , thankes sir
+Vikesh Kumar you're welcome
Sir really amazing explanation.... And one suggestion pls give the related videos or hint videos link in the top corner....
Thank you
Make a video to learn trans and spectrochemical series .. becoz Ur tricks are more realistic and easy to learn forever.
And try to make it before gate exam
+shalu goyal I'll try but can't promise before gate
Sir your videos are very helpful for csir aspirants .. keep uploading😊
Thanks
Thanks again sir for a imp video...pls take down some question of organic chemistry...for gate...and also for inorg , phys and spectro....revision questions...it will brush up our concepts...thanks
+Siddharth Suman physical spectroscopy I have covered all the question. Yes now I'll cover some organic spectroscopy questions.
Yup sir...I watched all ur videos...pls make org n inorganic videos...take questions from gate previous yrs...2010 to 2017...I alws follow ur channel...gate is really imp for me...or I will lose one more yr...completed my MSC in 2017..thanks a lot sir..
simply nice lecture sir I am truly obliged to watch it
+umendra khokhar thank you
Sir can you please make this kind of video on topics perturbation theory and variational principle. Your way of teaching is quite good Sir.
I'll try
Sir.. it would be nice if u upload more videos on spectroscopy and pericyclic reactions..
I'll keep that in mind
Nice lecture
Thank you sir ,, it's time saving , plz upload more trick video
thank you. Okay I'll try to make videos again
Very very nice explanation.... thanku very much sir.....!!

+subchain khan alright
amazing sir
sir plz upload video abt phase equilibria
+Younis Rasool thank you. Alright I'll try
mam plz shortcut for pertucbration theory
based questions
that will b ur most kindness
Mam pls make a video on essential trigonometric identities, differentiation and integration
Sir.. really good helped me a lot... plz make video regarding.. maths formulas regarding chemistry like integration differentiation.. ext... I need
+kranthi jami ok I'll try to make soon. Share this channel with your friends also that will be helpful for me.
In this equation what is the K=?
What is the formula for non-linear molecule sir (like C6H6)?plz also upload video on Secular determinant.
+Gopal Krishna Niyogi I'll discuss for non Linear in next coming vedios
Thank you sir for your dedicated video sir
Thanks sir.Hopping u will upload more videos on quantum chemistry sir
+ISHFAQ WANI yes I'm trying my best
U r best teacher sir.sir upload video on cyclopropane and cyclobutane
kindly discuss about the problems on partition function...
I'll try
Its very helpful sir... Sir pls make a video on pericyclic reaction specially sigmatropic reaction
+sam thank you. Alright
Gate 2002 the complexes V(C6H6) 2 and Cr(C6H6) 2 are both readily oxidised in air to their respective cations the number of unpaired electrons respectively in each are.. 1)0,0(2)1,0(3)0,1(4)1,1
+Jyoti Bhatt alright I'll solve
Jyoti bhatt ans is 3) 0 ,1 ..
How
For V(C6H6)2 5+12 =17e but in ques they asked if both readily oxidised in air to cation so 5+12-1 =16e similarly for Cr(c6H6)2 cation 6+12-1 = 17e (1 unpaired e) so ans is 3) o ,1 .
OK and thanks..
Thanks a lot sir.Sir there is one problem i know the values of cos 0,30,45,60 and 90 only.How to calculate other cos values ?can you please make a seperate video on this ?it will really be a help for other students also.Thankyou
You'll have to use calculator then, in Gate it's allowed so there shouldn't be any problem
@@CSIRNETGATECHEMISTRY OK thank you sir
For non linear I think it is a+2bcos(2kπ/n)... Here a is alpha and b beta
Dec 2014. The reaction of phosphorus trichloride with phenyllithium in 1:3 molar ratio yield s product A"a which on further treatment with methyl iodide produce s B. The reaction of B with BuLi gives product C.the products A B C are
Plz explain the solution of it
A will be PPh3 then it will attack Methyl iodide to give B product. Then Buli abstract one proton from CH3 group and finally you'll get PPh3=CH2 as C product. I hope it help you :)
Excellent explanation sir..
+Chiku Sahu thank you
CSIR NET GATE CHEMISTRY Sir what is the expected Jrf cut off for obc

I want to ask you some questions sir ....where to send the q
+ashish gaur you will have to write here itself
What will be the magnetic moment (spin only) of this species (n5- C5H5) 2Cr
How to find out
+Jyoti Bhatt try to fill e in mo diagram of metallocene, then you'll get the answer
How to find out oxidation state of Cr
Jyoti Bhatt oxidation state of Cr in (n5 -C5H5 )2Cr is +2 so 3d4 ..i think magnetic moment of this specie is zero if you fill electron in Mo diagram of metallocene there is no unpaired electron . what is your ans ?
Not in mo C5H5 work as weak ligand and filling of electron like as eg3, a1g 1 electron
