Happy teacher's day to the best teacher of the physics nd chemistry in advance❤❤❤ May u get everything in ur life....god bless u sir g💕 #Lotsoflove sir💜🔥
Happy teacher's day sir Itz u who rescued me every time I feel demotivate Itz u who made our concepts easy Itz u who helped lakhs of students to rescue them from the trap of tuition system Itz ur whose video never seem boring Itz ur notes motivation which keeps lakhs of students to be motivated Itz u whose goodness can't be explained.. There is no one who replace u (for me)
Sir i think that india will become free coaching country one day because of efforts of people like you proving quality education which others ask for lackhs to teach .
For +I your concept is ri8 ....but at para CH3 shows hyperconjugation too which is electron donating effect and due to which it is less acidic at para as compare to meta......
I also have doubt......on ortho and para position H effect will occur and finally para will be more stable than ortho because of the difference of alpha hydrogen...
Dear Teacher, Thank You For Continually Inspires me to do my best You help me strive for goals, I found guidance, friendship, discipline and love, everything, in one person ..... and that person is you HAPPY TEACHERS DAY!
Not everyone has a heart of gold, and such dedication- but you do! You’re a truly inspiring individual who has taught so much more than simply curriculum. Which is why I just wanted to let you know that your hard work, efforts, and care are much more appreciated Best wishes for this Teacher’s Day!💖
Sir Happy Teachers day ...you are like a blessing to us ...I can't thanks more to you , you are really doing a noble job ....I wish you get everything you want in your life ...and in the last I want to say you're really life saviour , I can't imagine my life without the existence of this great channel...✨♥️ PS: this is the very first time I'm commenting in any of the video on TH-cam....

Happy teacher's day Allakh sir. I belong from a very poor family and for me to even think of iit is like aukat ka bahar ka sapna.but when I come to know about u ,I decided to prepare for iit.thank u sir.u are an inspiration for the world . I promise u sir the day I will do something in life ....I will not forget to give it back to the society....may God send angels like u in this world to again make this world a place where human inhabitants 😊

31:30 onwards... Inductive effect depends on distance...and at meta position only inductive effect is functional...so in questions of arranging in order of acidic strength in case of effect of substituents on phenol, inductive effect must be given priority over mesomeric effect at meta position.

Happy Teachers Day to the world's greatest teacher I have met so far in my life. May God Fulfill all your dreams Sir and you remain fit & fine till eternity.
31:00 but sir inductive effect ke case me kya meta aur kya ortho Inductive effect toh distance pe depend karta hai na position se kaise stability decide hua?
Ortho Para directing group hai OH( +M dega) toh tum agar ortho para p EDG lagaoge toh repulsion start hojayega aur phenoxide ion unstable hojayega Aur agar EWG lagaoge toh phenoxide ion jyada stable hoga because of the presence of partial negative charge on ortho and para of hybrid structure of phenoxide ion.... Sorry for the previous answer ....it was kinda wrong😅
Firstly, +I grps- all methyl groups and those groups with a negative charge Then , -I effect - all functional groups and all groups with a positive charge. +M effect- groups which have lone pairs (also incld functional groups with lone pairs) , all methyl grps (due to hyperconjugation), groups with a negative charge -M groups- groups with positive charge, functional groups with no lone pair(eg NO2) Remember - halogens show +m effect and -I effect but their -i effect is more dominating while in other functional groups +M is more dominating if they show +M and -I ( -OCH3)
Happy teachers day alakh sir I have many things in my heart to say ,I want to feel the positivity by standing in front of you .I will put my all efforts to meet you one day and by touching your feet I will be blessed . Truly a real inspiration for me ❤️ Alakh sir ,thank you sir you are in my heart

Apka mehnat mein safal karunga hi karunga or apki mehnat zaroor rang laye gi ye student ka promise hain apne din raat mehnat karne wala bina koi swarth ke ek teacher ko Thank you , Yours student , Nilesh Choudhury
Exactly..and why inductive effect is more at ortho and para although its effect gets decreasing along with distance??so para should show least inductive effect..
For +I your concept is ri8 ....but at para CH3 shows hyperconjugation too which is electron donating effect and due to which it is less acidic at para as compare to meta......
I also have the same doubt....but i think Agar overall dekhe to acidic character is affected by ease of donation of h+.....and not stability of the product formed...and i think that donation of h+ is severely hindered by attraction from lone pair of oxygen
@@allinone3168 bro, inductive effect ortho aur para pr jyada nhi hai par ek baar iske resonating structure bana k dekho... -ve charge ortho aur para pr aata hai, isliye +I & +M [ya -I & -M] sirf otho aur para par hi electron density bada ya ghata skte hai... Yarr GOC dekh kar aao ya revise krke aao fir bolna (Aur haan, +I & -I para par kam hona chahiye kyoki vo jyada door hai) Anyone.. please correct me if I am wrong!!
Happy teachers day ..sir... Isi tarah humari madat karte rahiye ... Hume sahi rasta dikhaiye ... Aap ek bohot acche teacher k saath saath ek bohot acche Insaan bhi hai ... And you are always my favourite teacher ... Uparwala apka vala kare ..😇
Riya tum NCERT mei check kro page no. 329 pr tabke mei pKa value di hui hai aur Acidic nature pKa value k inversely proportional hota hai ,,,, so alakh sir ka ans Correct hai✅✅ 👍👍
Happy teachers day sir...its because of you I started loving physics . Watching your lectures improved my physics ..from just pass to the highest physics score in class .You are the hero of my life..A LIFE CHANGING TEACHER ⭐⭐
Sir you are too great .. We are lucky that Allah has send you in this world to help us .. May Allah bless you and give you each and everything what you want dear Alakh sir
Sir , it is because of teachers like you that we students dream to do extraordinary things! Happy Teachers Day Alakh Sir!! 💐Your glove duster is my mother's favorite 😁

Then , -I effect - all functional groups and all groups with a positive charge.
+M effect- groups which have lone pairs (also incld functional groups with lone pairs) , all methyl grps (due to hyperconjugation), groups with a negative charge
-M groups- groups with positive charge, functional groups with no lone pair(eg NO2)
Remember - halogens show +m effect and -I effect but their -i effect is more dominating while in other functional groups +M is more dominating if they show +M and -I ( -OCH3)
Happy Teacher's Day Sir...👨🏫

Dear Alakh Sir,
A very very happy teacher's day 2 u nd apke bare me jitna bhi bolu words kam par jata he , emotions jur jate he . Kab ap itna dur raheke bhi mera apna pan ho gaye pata hi nahi 6ala . Kabhi kabhi to so6ta hu koi itne a6e kaise ho sakta hain ? Par ap ko dekh kar Maine sikha hain ki kaise 1000 km dur rehke bhi maushya upakar kar na unko dher Sara pyar de na . Kash ekbar bas ap se mil pata ...
.. 😥 pata nahi kab mil payunga ki nahi par ap mere dil me hamesha idol banke rahoge. Apke liye jo mere dil me respect hain who hamesha rahega 6ahe ap kitna bhi dur kiu na ho. Apko mein pakka wada to nahi kar sakta but ha ek 6is hein jo main kar sakta hu- me kosish karunga ki neet me 600 + score kar ne ki or who ap ko gift ke tor par dene ki apke birthday pein. Apka mehnat mein safal karunga hi karunga or apki mehnat zaroor rang laye gi ye student ka promise hain apne din raat mehnat karne wala bina koi swarth ke ek teacher ko
Thank you ,
Yours student ,
Nilesh Choudhury

Happy teacher's day sir aap jiyo hazaro saal yeh mere Dil ki dua..☺☺☺and you are really a hardworking and dedicated teacher...so thank you
Sir, 32:13, sir o-methylphenol would be last sir because +I effect is greater than in p-methylphenol
Exactly..and why inductive effect is more at ortho and para although its effect gets decreasing along with distance??so para should show least inductive effect..
Yes....
For +I your concept is ri8 ....but at para CH3 shows hyperconjugation too which is electron donating effect and due to which it is less acidic at para as compare to meta......
I also have the same doubt....but i think
Agar overall dekhe to acidic character is affected by ease of donation of h+.....and not stability of the product formed...and i think that donation of h+ is severely hindered by attraction from lone pair of oxygen
@@allinone3168 bro, inductive effect ortho aur para pr jyada nhi hai par ek baar iske resonating structure bana k dekho... -ve charge ortho aur para pr aata hai, isliye +I & +M [ya -I & -M] sirf otho aur para par hi electron density bada ya ghata skte hai... Yarr GOC dekh kar aao ya revise krke aao fir bolna (Aur haan, +I & -I para par kam hona chahiye kyoki vo jyada door hai) Anyone.. please correct me if I am wrong!!
Happy teachers day Alakh Sir♥️♥️ You are the best

Happy teacher's day ❣️ Sir !
Happy teacher day sir ji ☺️☺️☺️☺️☺️☺️☺️
sir goc m aapne btaya tha that +I effect depends on distance then at 31:40 order should be a>c>d>b .do tell me if i m wrong
Riya tum NCERT mei check kro page no. 329 pr tabke mei pKa value di hui hai aur Acidic nature pKa value k inversely proportional hota hai ,,,, so alakh sir ka ans Correct hai✅✅ 👍👍
It should be d >c >a> b
Happy teachers day sir...its because of you I started loving physics . Watching your lectures improved my physics ..from just pass to the highest physics score in class .You are the hero of my life..A LIFE CHANGING TEACHER ⭐⭐
