#Trick 1:-[First ques] n- given in the ques. For balmer series:- n-2. For any series we can use this trick n - ni(lower value of b acc to respective series). #Trick 2.[2nd ques]. Red has the highest wavelength, by seeing the diagram only we can say tht line 3 to 2 having the lowest energy means highest wavelength. #Trick3 [3rd ques] Check num of peak = n- l. In the figure we can see two peaks and by formula n-l we can say 2s is hving two peaks. Hence b opt is the ans. Thank you so much dost ❤ Love uh infinity moles❤️🔥

Me center me beth kar ye video dekh Raha hu 💀

Thanks a lot. These videos really do help. Looking forward for more of these kind of videos

Thanks Alot Sir

Amazing sir just amazing 👏 Thank u soo much 🙏🙂

Please bring more tips and short type content very helpful ❤❤

😮❤❤ need more videos like this ⚡

Sir at the same time you uploaded the video I was revising atomic structure chapter and was in need for such tricke

Bonus point for second question: Red light emitted means visible spectrum, i.e. Balmer series, and only one of the lines was reaching n = 2 EDIT: I was mistaken, this is not correct, pls read comments to understand

this content are really help us

Thank you so much sirji

Arvind sir , its a request that please bring short cut trick videos of every chapter for jee 2024 aspirants🙏🏻

Sir same for mole concept

Sir please upload such kind of video for solutions, equilibrium and mole concept. Thank you.

Mere se bhi ho gye in less than 5 sec as 1) qs are easy and 2) concepts are clear. Acc to me this would be beneficial for school and mains only. BTW logic for all Trick 1 : we are analysing transition of n_higher (from where we start) to n_lower (given final destination, here visible => balmer => n_lower = 2). if we visualize the final transition, each's n_higher decreases by 1 every time (here 6->2,5->2,...,3->2) Trick 2 : Sir se badia main kya hi exolain karun iss wale ko (my input would be ki if we remember that energy is inderictly proportional to n^2, then its logical, jitna niche transition, utna bada energy gap) Trick 3 : My method is little different. I count number of times the graph touches the x-axis, so it gives me number of radial nodes, then i have remembered the nodes formula

Great 🙏

sir we want more short and sweet videos like this

Wow nice trick ❤

Thank you so much dost❤❤

Sir physical chemistry calculations are vast and almost undoable without calculator. pls show us the way to solve them down completely without using calculator even once. practice isn't bring that skill, pls help

i had a doubt reagading orbitals , will someone care to explain , so for 2s its meant to represnt the probability density for the second shell right , so why then in its visualization 1s is also included , and then its radial node becomes 1 , i mean if its like suppose aluminium for example wont that nodal region also have probability of finding e- because of all the different orientations of p's , someone pls help

Thx dost I am going to give a regular test today and this chapter is coming

Thanks dost

Thank you dost ❤❤❤

thanks dost

Sir graphical Schrodinger mein hum radial node dekh kr bhi toh kr skte hai jaise is question mein graph x axis pe ek baar touch kr rha hai matlab 1 radial node aur 2s ka (n-l-1) se 1 radial node hota hai mtlab ye match ho jayega

While defining no. of unique/visible spectral lines we always rend to forget that sample is given or atom is given... That's the click of the question 🤍🪂

Thanku sir

Sir pls give some shortcut trick for phsi questions

Could you please make such shortcut video for physics too pls?

Dear Mohit Ryan/Arvind Kalia/Tharun Sir , can you please put the English subtitles. I had commented the same in one of your the underperformer IIT JEE Aspirant videos sir. Please sir 🙏🙏🙏🥺.

Sir, please make a video on logarithm and modulus.

When did Haris Rauf Started Teaching Chemistry 🤯

Literally dost, these qns gave me confidence I'm happy that i was able to keep up my pace with u, & also did learn another approach to the same qns LY3M ❤❤ I'm loving this series 😁

❤❤❤dost and bhai🎉🎉

No. Of spectral line =(n2 - n1) (n2 - n1 + 1)/2

1 more trick for ques 3rd is that counts only the roots of graph which is equal to radial nodes

Sir please make short trick videos for other chapter also 🙏🙏

Doubt for 1st question: Sir, with due respect, Jo aapne answer Diya usme to answer ye bata rha hai ki kitni lines balmer series me fall karengi but mene padha tha ki balmer series me saari line visible region me nhi hoti sirf first four line hi visible region me aati hein. To lines in visible region to kabhi 4 ko extend karni hi nhi chahiye but acc. To your explanation, lets say n=12 and then balmer series me to 12 = 6 lines hongi but visible region to abhi bhi 4 hi honi chahiye na. Kyuki balmer region me sirf starting ki 4 lines hi visible region me hoti hein. Bas agar n≤6 hua tabhi vo formula valid hona chahiye kyuki agar aage ke shell ke liye vo balmer series ki total lines batayega na ki visible region ki I think ki vo formula number of line in a series ke liye hein but visible range ke liye tab Tak valid hai jab tak n≤6 na ho Agar n>6 hua to vo number of line in a series ke liye to sahi hoga but visible region me uske baat hmesha 4 line hi aayiengi Sorry if I said something something bad Please correct me if I am wrong❤️

1 que mai agar infrared region diya toh kya karoge guruji ?

isocyanic acid is a electron widrawing group how pls tell me

Sir last question m apko kisa pata chala kie 2S hie hoga wo 2P v tho ho sakta h na

Thank you sooooooooo much sir yahi question mere shift me phasa tha maine 5s ke andar solve kar diya ❤❤❤❤❤❤❤

Sir are these lectures enough for jee

❤️🔥❤️🔥❤️

Sir same with mole concept

Osom

You can calculate no. Of peaks directly by l +1 (where l is azimuthal quantum number).

🔥🔥

Shouldn't we include the reading time in solving art of 5 sec also😅

👍👍👍👍👍

Thanks Sor

Plz give same trick for mole concept questions

Sir jitne chapters ke aese video la sakte la doo

sir jee 2024 ke liye peter sykes se mechanism padhlu? i have faith ki i can do !

❤❤

Nikhil sir had taught us the first trick❤ Arjuna jee 2025 pw attendance here 👇

Countinue this series ❤❤❤

Lvu sir

W Channel

Sr 2s wala smajh nhi aaya 2p kyu nhi ho skta

wow

Pls take class on English bro😮😮😮 we also like to learn😊😊😊😊😊❤❤❤❤❤

Please for mole concept

HELLO DOST ❤ . DOST WE WANT THIS SHORT TRICKS SERIES ON ALMOST HIGH WEIGHTAGE CHAPTERS IF POSSIBLE . LY3M❤❤❤❤❤

Sir please use English so that we(persons who don't know Hindi) can also got benefited

Sad reality of jee aspirants is strategy videos get more views then compared to videoz like this

Sir iam in class 11th jee asiprant But sir aapne jo starting tricks batai main pehle se hi aise hi questions karta hoon but phir bhi atomic structure ke 50 - 60 % questions hi solve ho paate hai

Sir make this for vectors😢

Sir pls make also revision video for chemistry hole chap in one video

Dost i get confused in molality ,normality , molarity, please do something

ESI video exam ki ek raat pehle hi kyu milti hai😢

Sir can you make a video in English

I think first right answer is '5'

Muje laga editing sikha rahe ho...

dark truth is that the teacher not including' the reading and understandng time that takes in exam

Physic ke bhi cls kairee sir

Sir please hard adv level ka qus par Viedo ki Jiya ye Viedo ka qus bahot easy tha

O bhi exam me concept yaad hi nhi rahta trick Kahan se yaad rahga😂

second ques mie toh kuch zarurat bhi nhi thi trick ki balmer series ki ek hi line thi aur pucha tha red kon emit kregi aka visible region 😂

Bhaiya apko puppy Dena ka Mann kar raha hai, yehi chaiye tha 🫠 mereko

Nikhil sir students also know this trick

Sir woh questions toh aapko pata hai , live video Mai new mock test questions 5 second mai karwaye

Sir pls talk more in English👍💯

01:15 . I solved this problem in just 3 sec 😂

Sir mole concept

Sir vedantu kyu chhora new waale sir ka kuch samajh nahi aata hai

For 3rd question Formula is n-l-1 For 2s N=2 l=0 2-0-1= 1 The graph also touches the origin only once Hence 2s is ans

bhai 1st ka answer to 6 hai....

First comment

First view

N2_n3 ho gya bss

Thanks for wasting my 7 minutes

69 comments complete 😅😮

Ye trick hai muje to lagta tha yahi method hai 🥴

Meanwhile ye trick toh khud hi invent jarke ysse kar rahe the pata chala ki ye toh pehle se hi exist jarti hain...
