Happiness is.... Watching a short video after a long one:)

I love these small lectures 😅😅😂😂

He just takes the TOPIC'S level from 0-100 ...!!!!!🎉🎉🎉🙏🙏🙏

I left my school online classes and came here because alakh sir is best not only in physics but chemistry also

Short lecture feels like a reward after watching the long one !!😅

watched 10 videos of organic chemistry today and finally happy with this small video..😁😁 satisfaction😊😃

Great teacher, I only watch your video in 12th class without joining the college. And now I top IOE examination. Respect from Nepal 🇳🇵 .

Sir 12th me aap hi padhaiyega Physics and Chemistry .aap ko dekh lene se hi aur aapki aavaj sun lene se hi topic aasan lgne lagta hai. Ek nayi urja mil jati hai.

Who was your chemistry teacher?? Thanks to him/her also

Tareef karu kya uski, Jisne tumhe banaya, Oh physics wallah ! Love you Alakh sir ji ❤❤❤

1:55 A very good evening to a very good morning ! Dedicating a whole night to this man is really WORTH IT ! 🔥😌✌🏻🤟🏻

If you are a biggest fan of physics wala sirr.. then like thoko yrrr

Outstanding teaching method ...guru ji Extra talented good gift.. Help us like this only😍😍🙏🙏

सर पहला राजा देखा है जो खजाना लुटा रहा है🙏🙏 Thank you sir 🙏🙏

Weakest base or stable anion =best leaving group

Sir , your method of teaching is great . It helps us lot . Thank you so much 😃😄

4:20 Love when he says " Aab ate hai kyu padhna hai ye leaving group"

Alakh ji you are doing great

2x me dekhne ka alag hi maza h😅

aap sach me bht acche hain sir. comments me kuch log zabardasti ghalat words use karte hain. lekin unka number aapke fans ke mukable 100 me 1 ka hai. we really love you sir

Can't explain in words .... How amazing u' re

Yaar hme to ye nhi samjh aata ki aese konse 54 log he jinho ne sir ke video ko unlike kiya he...😏 bt really thanks a lot sir.. We all love u sir ji.

Sir we don`t feel that u r only physics wallah u can also teach Chemistry perfectly😍 Love from Pakistan✌

No one like you in this universe

These lectures are gold for better understanding of concepts of organic chemistry. Alakh sir's explanation are on another level! He takes every concept in depth and easy to understand. Believe he's THE BEST TEACHER out there.

PW: length 28 mins Students: Itni khushi Itni khushi 😁😁

Kamaal ka lecture sir!! Aaj to ekdam majaa hi aa gya😁😁

Thousands and more prayers for you sir you are the best!

15:32 Stability: H2O > NH3, basic strength: H2O < NH3, better LG: H2O > NH3 & acidic strength: H2O > NH3.

Sir kaash apke jaise aur teacher ho Honest 😁😘❤️❤️🙏🏻🙏🏻🙏🏻👍👍🙏🏻🙏🏻🙏🏻

All teachers in the beginning speaks hii guys but you hello bachho........ 😍Amazing

yess i m so excited for more organic videos

23:37 EWG increase the stability of anions and EDG increase the stability of cations.

Hatsoff to u sirf for ur contribution and love for us...may God bless u and give very good health...

Thank you so much sir. May vishnu always bless you.

No word's to say about your teaching sir just amazing 😍🤗 lectures thank you sir for your kindness😊

Kya bath hai sir 1M se 1.5M bhot jaldi ho gye. Congratulations 😎🤘🏻

26:41 best beatboxing 😍🤣🙏

I was really excited to watch this short video ...♥️

Sir u r gr8

U played both the role very well Physics wallah as well as chemistry Wallah... I need only Bio Walli

Aaj 25 December hain saab ja rahe hai church aur me sir ka lecture dhek rha hu class 12n ke liye jarurui hai❤❤

Sir ke liye ek bada salute.

Sir aap mere liye aaese guru ho jaise aap mai karn hu aur aap guru parashuram ho mere liye jai ho gurudev ki....

Preparing these lectures is not easy....salute to you, Sir.

He is super amazing. He's chatpata phy-chem combo. Amazing man.

Small and sweet lecture

Mujhe toh ye samaj nahi aata ki 2019 ke pehle log IIT mein nikalte kaise honge bina SIR ke videos dekheeeee🤔🤔🤔🤔🙏🙏🙏🙏🙏❤❤❤❤❤❤love you Sir. Thank you Sir 🙏. 💕

Awesome sir 👌👌 👌👌👌👌👌... Way of teaching..... Concept clearing....

Thank you sir for your consistency of series. 👍👍👍👍👍👌👌👌👌👌👌😚😚😚☺😚😀😀😀😀😀😍😍😍😍

U r best teacher in india

Best lecture I found ever about leaving group

Kisne socha thaa ki physics wallah 3 saal ke baad 101th unicorn of India ban jaegaa

Sir teachers day became happy because of you .🌚🌝

Thank you sir ye concept clear ho gya aap jesa best na kisi ne padhaya h or na padha sakta h

Sir, i million ke tayire kar lo 😘😘

Sir apke gaane bahut mst lgte heee gaate rha kroo😍😍

Best of luck every 12th class students 👍👍

7:56 sir apne phle ke lec mai bata tha ki electronagative atom mai minus charge stable hota hai aur yaha f- jyada electro negative hai to plz koi reply karo if someone knows the answer!!

Thank you very much sir for your great efforts😊😊😊😊😊

Watching this small lecture at 4:30 am

Thank you sir 🙏 your lectures are very helpful to students.

Acidic strength toh down the group decrease hoti h 🤔 toh HI most acidic kaise

EAST OR WEST ALAKH SIR IS THE 👍💯

Aaj bhi koi topic sataye Yaad aate hoo tumm Yaad aate hoo tumm 😅😅😅😅😅😅😅 Respected alakh sir ♥️♥️♥️♥️

Sir Ye lecture samajha me nhi aaya

Jab koi nhi milta aap k lectures milte hai💓

Feeling like on top of world When sir says "Eqi. Me pada tha...."

SIR JI THANKS.... WAS EAGERLY WAITING FOR YOUR LECTURES...... LOTS OF LOVE FROM HIMACHAL......

Sir plzz ask awasti sir to speed up his videos plzz

*U R AN AMAZING TEACHER* ❤❤❤❤🖤🖤🖤🖤🖤

Sir aapne rate of friadel craft reaction me leaving group tendency alag bataya tha

Sir ka video like krne mein alag hi level ka maje hain

Sir please do this chapter as soon as possible

24:00 Yeha pe Last (c) compound Mei hyperconjugation bhi haina.. what about that then?

Sir plzz hydrocarbon or ray optics start karva dijiye 18 sae exam h plzz sir

These videos are still the best even after 5 years!!❤ Who is here for NEET 2025?😊

Great teaching 🥰🥰

Thank you so much sir...thanks for such a great job....world's beautiful creation is Alakh sir ...lots of blessings from kashmir...

You are great bro.I was demotivated due to course pressure but watching your 28 mins video make me feel easy to cover it😍.

26:17 Benzene sulphonic acid(C6H5 - SO3H) is A) a strong acid, B) a weak base & C) a better LG(stable LG).

ghum frr k alakh sir k pass hi aana pda.. no one can't explain better than him..👍🔥

Alakh sir is the 💓 beat of every student

Respectively thank you very much sir in this corona virus situation you must help me 💗💌💗

Sir thank you for this wonderful lecture🥰🥰🥰❤️❤️❤️

18:20 sir, EN pe + charge hai to across the period stability decreases but more stable will be removed na! And called leaving group so rate will be more in the reaction where stability more, so vo reaction me N ke pass plus change hai which means it's more stable than o+ so I'm confused!

sir you are gift for us(che students) love you sir ......

Sir, you promised the lecture regarding the electrophilic substitution on how to define major and minor products between ortho and para positions in the previous lecture to this but now you started nucleophilic substitution.

At 24:37 chlorine will give its lone pair inside the benzene ring and create (-) at para position .... So it will be the most unstable .. Am i right ??

I never get bored while listening to his lectures

Sir,25:20 I effect 3 se jyada carbon tak travel nahi hota To A&C equal reactions dikhayenge

Who is watching this during quarantine?

Sir apne bola ke benzene sulfonic acid is the strongest acid in organic chemistry...so sir.. is it the weakest base in organic chem!??

Sir phir hum aise bolt skte hain ki Jo sabse acha acid , uski leaving group tendency high

Thanks for helping all Students 🙏🙏.

Pace of my life - 26:43

Sir aap se puri physics and chemistry padhe hain.aap se bdhiya koi nhi pdhata

In inductive effect.. We learnt flourine is more stable, it has more -I effect, hence it's more acidic.. Then here iodine is? How? Can someone tellme

Very Good Afternoon Sir! 🌞
