Quantum Chemistry: Variation Theorem || Easy Approach || Solved Problems

[@ArtePragya]

Such an incredibly amazing, simplest and complete explanation. The best video on Variation theorem. I have struggled so much in understanding this theorem. But after watching this video I am so much in state of solving questions based on this. Thank you so much. You are a wonderful educator. U explain every little detail and point with so much ease and patience. And yes, i am from biology background. Yet in first go, i understood it so well from this video.

E^2-3E-4=0 and min energy = -1

[@rajeshkumarbehera9834]

Sir the way you explained i would like to give 1 lakh likes or more even if youtube had that option of giving more than single like. Thank you very much sir. your way of explanation is too much good. Hats off to you sir. And sir please make more videos from quantum chemistry because we students are from very unprivileged area and it is because of your videos we are learning chemistry.

[@AllBoutChemistry]

Thank you brother, I'll try to upload more videos soon

[@AJITKUMAR-wr7cj]

Your efforts are always appreciable

[@ramkarthick3258]

Ground state energy is -1 Excited state energy is 4

[@jeenajoseph2407]

Most awaited video. I was searching for this type of a calm video, with a lot of thanks from kerala.

[@shashikantsajan5773]

Sir waiting for perturbation theorem ....nice explanation Sir.

[@SD-hz1bs]

You are an excellent teacher Sir....Truely Inspirational....keep going....All the best wishes.....

[@vineeshabathini5333]

You are doing Awesome work Sir.. All your Classes added thousand fold Confidence to our Preparation..Thank you So much Sir..

[@priynkajaale8113]

Wow sir very nice thanku sir ji...🙏🙏😊😊

[@donaldegwang5896]

I love ur teaching skills

[@aravinddhandu778]

Thank you so much sir. Try to add some more topics from quantum chemistry why because quantum chemistry is huge topic even maths background students are also not able to understand thus.

[@aditiboruah7793]

Sir you are too good.

[@narendrarawat1481]

Great great great sir... Sir iam a big fan of you...

E = -1 and 4 And min energy -1

Thanks for that video sir 🙋🙋🙋

Very nice 👍

Thankyou so much sir......sir please make a video on H atom

[@nibeditanath4117]

Sir it is really very helpful. Thank u sir..

[@g.suresh4586]

Thank you so much sir.,I understood clearly.,I like your way of teaching.,and the answer for the last question is -1

[@SaagaaVanam]

I have one doubt sir...Sorry if I ask as misunderstood, h cross c /2m in question...But how did it converted in 32.24 min h cross ^2/2m.. sir please check whether the given E value correct or not ..In question part..

[@pratikshamishra6411]

Please upload more videos on youtube before upcoming exam.

[@sumanmondal6598]

Thank you sir...

[@gourabsaha1078]

Is the energy of trial wave function also greater than the excited state?ny xplanation or something,just wanted to know

[@Neha-gz5fc]

Sir in the last questn , the value of c^2 = m^2w^2/4h and in value of c where h^2 is coming out

[@dhivyapaaru2183]

How h^2 came.can u plz explain

[@rajsekhar007]

Sir the answer of the question you gave for our practice was " -1 "....Sir, I think there was a mistake while solving i.e part-4 ( Maxima and minima kind of question) when dE/dC = 0, how h-cross will come over there ...???🤔

[@gwgamingwithbot4507]

Can energy value be negative considerable

[@RameshKumar-gw9tm]

Because of Energy value = h cross (2) c/ 2m +mw(2) /8c but sir forget only wrote on that h cross c / 2m + mw (2) / 8c that was mistake sir made

[@nagendrankubendran4267]

Thank you sir

[@electronclouds8104]

I think this is the only one vdo that approaches in a very soft manner. min energy -1

[@rajibdebnath9896]

Sir you mentioned the trial wave function that has more linear perameter, will have the nearest value of E exact. And E trial is greater equal to E exact. But u did not mention which trial wave function have greater E.

[@AllBoutChemistry]

If you have two trial wave functions, one which is made of linear combination of two wavefunctions having energy E1 and other with linear combination of 3 wavefunctions having energy E2 then energy of E2 will be closer to E(exact) and E1 will be away from E(exact). Among E1 and E2, E1 will be greater. Overall order will be E1>E2>E(exact) I hope this was helpful

In last ques how it become h cross square at dE/dC=0

[@naraharigunti832]

In question only it must be h cross square by 2m

[@shiwanirana5048]

thanku very much sir

[@SumanSharma-cn6om]

Min energy is -1 Nice sir

[@ugcourse3776]

How are you writting hcross square ??

[@gauravjyotid.kalita3417]

I found the minimum energy as -1, please tell me if it's true, and also tell if practicing these three or four types of questions for this topic is enough, or do I need to grind more

[@chemikamesh4788]

The quadratic eqn is E^2-3E-4=0, then it solve gets 4 and -1 min energy is -1, And another... Pls tell brother when Ur preparation especially this chapter, how u prepared strategy...

[@manishajain1078]

Aap pls perturbation theory pe b upload krdo..with triks nd all

Sir, at 33:24 time you had written down the wrong expression of dE/dc .

[@shuklasanju572]

Nice vdo

[@kumarirashmi8293]

Sir in last question min. Value of energy is -1 hai.. is it right

[@manjukp5498]

sir, at 33.18, while equating dE/dc=0, how h-cross became h-cross squared?

[@souravpan3068]

same question

[@muthiahpillaipalanichamy3939]

@@souravpan3068 He made a mistake. The starting eqution itself carries h-cross squared.

Sir in trial wave function problem E= h cross(2)c /2m but u wrote on that h cross c/2m in that way doing that root h cross obtain plz once check that

Sir in last question from where h cross has came

[@chemistry-basicstoadvanced714]

in question last but one ... it should be hcross squared otherwise the answer is wrong
