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.

[@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

[@ishanisaini9481]

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

[@jeenajoseph2407]

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

[@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.

[@vineeshabathini5333]

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

[@ramkarthick3258]

Ground state energy is -1 Excited state energy is 4

[@shashikantsajan5773]

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

[@AJITKUMAR-wr7cj]

Your efforts are always appreciable

[@SD-hz1bs]

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

[@priynkajaale8113]

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

[@donaldegwang5896]

I love ur teaching skills

[@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

[@KrishnaSharma-ik3sm]

Thanks sir 🙏🏻🙏🏻

[@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..

[@Dharmenderkumar-tk6gn]

Sir please make vedio on stastical thermodynamics ...

[@dipensen4138]

Sir I requeste you to create a video of perturbation theory ....

[@ganeshgs2241]

Superb Sir

[@pankajadhikari8072]

Sir perturbation theory pr jitna jldi ho ske bna dena video plzzz

[@chintadasatyavathi4960]

sir your explanation is very nice thankyou so much

[@electronclouds8104]

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

[@gourabsaha1078]

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

[@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

[@aditiboruah7793]

Sir you are too good.

[@kanakkalita9509]

This pen and paper method is the best in the world

[@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

[@yaduvanshibhumi2614]

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

[@pankajadhikari8072]

E = -1 and 4 And min energy -1

[@pankajadhikari8072]

Thanks for that video sir 🙋🙋🙋

[@AllBoutChemistry]

Very nice 👍

[@guntinarahari3031]

Thank you sir...Your explanation making the concept very clear...

[@rachanasharma6080]

Minimum energy= -1 thank you sir nice question session 🙏🙏

[@narendrarawat1481]

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

[@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...

[@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

[@rajibdebnath9896]

@@AllBoutChemistry thank you sir

[@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

[@RameshKumar-gw9tm]

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

[@silpasree2170]

Very useful...Thank U So Much Sir..

[@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.

[@ugcourse3776]

How are you writting hcross square ??

[@chemistry-basicstoadvanced714]

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

[@nibeditanath4117]

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