No.8 and no.14 are wrong because halogens show +m and -i effect with max -i in f and min +m in f and +m effect is inversely proportional to acidity as it increases e- density on ring correct order should be f>cl>br>i
Yeah!!
Yeah
Aise hi questions wale videos bnate jao.. Pdhane wale videos to already kafi hn RUclips pe.. Pr aapki trh questions wale videos kafi km hn..thnku..keep it up👍👍
Best discovery I made for organic chemistry after PHYSICS WALLAH👏🏻👏🏻🙌🏻🙌🏻🤩🤩
You may visit komali mam channel ... You start loving chemistry....
In 8th the order ll be F>cl>br>i
8:09 sir but minus inductive ki series me to Order F > Cl > Br > I hota h to aapne ulta kyu likha?
Que. 3 ulkta hai kya
@@ArtisticMind0003 size par depend kartr ha I
Sir actually 1°>2°>3° ryt?...so it will be b>c>a>d ryt.....(in 3.48)
Really amazing sir.... All concepts are clearly explained... You vanished away all my doubts.... Keep uploading such videos.... Thank you.
Example 8 mein apny kaha Halogens -l or +m effect show krein gy Lekin example 14 mein apny kaha -l or -m show krein gy ... ...?
Sir please explain the reason
In question 8 why iodine containing compound is more stable?
Abhi tk utube pe jitne bhi maine dekhe unme se apka
one of the best
Sir 6th ma -I effect ka basis par nahi kar sakte kya? Jaise 3rd wale ma 3 NO2 ha toh sabse jyada -I effect.
Sir plzz clear my doubt.
Sir please explain why in example four, acidity of a is greater than c. If we see resonance due to (a) negative charge will go on electropositive carbon whereas in case of (c) it will be on oxygen. So why c shouldn't be more acidic than a
Sir in example no. 8 the order of -I effect is F>Cl>Br>I then why is the order of acid strength exactly opposite?
CRAZY - OTK y r right
Kevel -I nhi woh -I aur +M ka combined effect hai
-I ke saath +M bhi hoga, that's why iodine is more electron withdrawing
@@harshulmathur2620 but won't +m destabilize the conjugate base? Due to this the order should be exact opposite....pls explain am getting really confused with example 8
Due to the involvement of d-orbital resonance
Conjugate basic strength is inversely proportional to acidic strength!
Sir question 8 mein koi vacant d orbital ka concept bhi hai kya.
Wo plz. Btaye na
And question 9 mein order ulta kyun ho gya sir inductive effect ka.
Koi reason uska btye na
Sir aapne ortho effect kha pe smjhaya h.. Video mil ni rha
Sir please explain me in ortho effect less resonance more acidity kaise hoti h
ruclips.net/p/PLFKdq9r0Uy8d21Dby4pkZC-0jx9DRgkGi
You can find or thi and sir effect here
Sir u said that upto phenol all reacts with NaOH , does that mean including those which reacts with NaHCO3 also
No
_i effect to flourine ka jyada hota hai to lski withdrawn power to jyada hogi to sir aapne example 8 me iodine ka withdrawn jyada kese ho gayi &just example 9 me flourine ka withdrawn jyada batayi plz sir ise explane Kare or sath me yeh bhi batayega ki sir effect acidic strength to kese increase karta hai
Sir ne bolaa tha naa ki agar -I or +m dono aajye tb I>br>cl>F hoga agar sirf -I hi hoga tb hoga F Cl br I
Can anybody explain to me that in Q 8 , 9 both cases halogens present but why the stability different for them.?
Sir q12.... In 3rd compound No2 ka -m nahi lagega ...agar NO2 meta m hota tou lag jata NO2 ka -m ...sir dnt give wrrong info
Amazing content sir😍😊 could by any means can I get this PDF please sir??🙏🏻🙏🏻it will be very beneficial
Sir plzz doubt solve kar dijiye... P Halo carbolic acids ka toh highest p chloro acid Diya hua hai
Amazing sir it's best lecture for me about acidic strength.
sir..in no.14 ...2nd compound is more acidic than 1st compound dùe to p.pie..d.pie bonding..
Question 8 answeris wrong
It should be 3>4>2>1
Sir i am telling you agar aapne video banaani band kar di toh mujhse bura koi nahi hoga. Aap hi ne mujhe itne acche content ki aadat dalwa di ab aapko meri aadat ko pura karna hoga
Give me the name of next topic you want to study
Sir can you tell me reason for the example 8.please reply to me. Many students have same doubt
Sir No. 8 and 14 main kiya difference hai.... ek main iodine ki I effect jada ek main kam aisa q???
Ek ke Sath OH group he wo Electron donating group he... And dusre ke Sath COOH he wo electron withdrawing group he es liye
I want to know both acidity and basicity of organic aromatic compounds by applying resonance
And inductive effect n b4 that have proper description about hyperconjugation resonance n inductive effect with ortho para activating deactivating grp meta directing grp with how to know 2p-2p n 2p-3p with electron density n displacement description after that it will be easy to know about acidity n basicity
Sir I have doubt in Question number 8 please check it..
Sir in question no 14 para fluoro Benzoic acid is more stable than para chloro Benzoic acid and so on....
sir do you also have video for basicity
which bok should i refer for electronic effect of halogens responsible for acidity of phenols and benzoic acid
Sir e.g no. 7 option C ...here is exception when nitro grp attach to para grp it show (-R) effect but you wrote (-I)🙄
Sir...pera helo phenol me..kyu.... inductive effect ko mesomeric effect se..kummm..bataya gaya. Hei...
If only for helogen inductive effect is more effective than mesomeric effect ...the.....pera floro. Phenol ....pera iodo phenol se jyada....aecidic hoga na....
Sir acidic strenghth increase Karta h ? My sir told that it decreases acidic strength and increases basic strenght . Please clear my doubt...
SIR inhibits low quality resonance , but the resonance still occurs between the two oxygen atoms which is much more effective ,, hence acidic strength increases
at 3:41 why is one degree carbon more stable than 2 degree carbon
Sir thanku so much. This very useful to me. Now i have no doubts in acidic strength✌️👍👍👍🙏🙏
Thnku sir.....aapka sab example kafi important hai
Your explanation is superb and covering maximum portion of area with different examples. I am searching a lot of channels finally i got the best one, thank you so much
The Best video I found for acidic strength 😍❤
Can u clear this doubt how halogen shift acidity order when it is in meta and para position?
@@subhashreesethi8186 ask chatgpt
Sir plz nucleophilicity ka video banayega or iske order ko solve kese kre explain it
Nise of you sir it's very helpfull sir clear all dought thanq,,,,,,,,sir
Most welcome
Sir question 17 me sir ke chalte resonance effect kewal kam hota hai na ki pura khatm
Sir .I have no word for this great help..love u paaji
Sir why are you not uploading videos now??your videos are very helpful??
Sir please at the end of the video summarise all the concepts used for comparison 👍🙏🏻🙏🏻
Clorien ka pera position par +m effect lagata hai so simple ka pahale hona chahiye acidity order me
Mja aagyaa sir thanx ❤❤❤
On Q13 ,11:16 shouldn't the order be 1>4>3>2?
Bhai voh +I and +H show kr rhe h nah isliye.... (+I aur +H vagaira unstable krte h) so i think sir ne sahi kiya h
@@bethelegend8924 Haan. Udhar +M/+H bhi operate hota he CH3 group ka. I know now.
Anyone know the reason for 8 que
Sor 12ques. Me h bonding at ortho ni hogi????????????
please give the link for previous video on acidic strenght
Strong acid Ka conjugate base weak hota hai nn??ya strong
Weak hota hai
in example 9 F is more electronegative then I then how -I effect more of iodine
Thanks sir this was legit helpful...I was confused when to prioritise +M & +I or other such combos, but, after watching these solved examples I'm able to solve acidity-basicity questions pretty easily...Thanks for this awesome video!
❤️❤️❤️ thanku sir .... this video really very useful for me and clear my all doubts through this video ...thanku so much sir❤️❤️❤️👍
Sir thanks a lot for explaining everything in short😊
F ke pas vacant d orbital nii h toh how it will show +M
thanks for singlehandedly saving my life, you're the real deal, no joke
Plzzz sir ...steric hindrance affect on the basic and acid ka video bna dijiye....
Already bana hai
U r very good sir.....uniqueness hidden inside you
Are bhaiya question no 8 me I effect Ka order kaise change ho Gaya?
M effect show karne ke liye lone pair chahiye hota hai na
sir after complete class 11 and class 12 organic chemistry will u pls upload physical chemistry specially equillibrium and othhers along with question before the end of november pls reply sir
+LARA DIGITAL sure soon I will upload chemical and ionic equilibrium
Demaak khul gya itna accha btaaye aap 😊thank you sooooo much sir 🙏🙏
Beautifully explained all doubts cleared.
Thankkk u veryy much sir😇😇
Your videos are super really..i have watched many..but it is most usefull...
Try to teach us chemistry for neet 2019 ..
Sir no.12 -cooh group being meta directing, why cant the order be 2>4>3>1
It was realy very helpful video. But i have a doubt that in question no.14 how halogen will show -I and -M effect?
By mistake,Sir spelt that wrong...it is +M effect
@@SenpaiSan then the correct acidic strength order should be decreasing left to right. Am I right?
Yes, u'r correct
Sir SIR effect mtlb? M kaha se dekhu
Very helpful q sir ...thank you ❤❤
Is sir increase acidic strength in only carboxyl grp
Great lecture all concepts cleared upload more videos of this kind
Sir how you record your videos
I want your help
What is SIR effect in question no 16
So nice explanation .....👏👏✌👍👍
4:20 whybc is not more stable than a...help
Coz a shows extended conjugation
how in case of COOH group mesomeric effect be affected?
How are Halogens (in Q8) considered to be +m groups ?
they can donate lone pair
Halogen are always weakly deactivating group so if word deactivating comes then be sure it shows -m effect so x are electron withdrawing group always (keep remember this).....see in this question OH of phenol is +m that means it increases electron density on ortho and para hence at para position halogen can see there is e density so they will withdraw electron from that para side (because halogen shows - m effect ) ..if halogen are showing -I and -m then order of electron withdrawing tendency is f(cl(br(I ...bt if halogen shows on -I effect than order is f)cl)br)I.......one imp point keep remember as halogen are -m directing (weakly deactivating ,e withdrawing )bt they show ortho ,para direction in electrophilic substitution .....this is a big exception keep remeber
@@roamingo5283 thanks bro
I was looking for this video only... Acidic strength of all electronic effects.. and a good explanation.. Thanks Sir
12th m ortho effect kya h ???
Sir., please make videos about ortho para meta directing grps🙏
Very effective and helpful video
Simply wonderful sir.
All confusions clear before mains ....
Thanks 😊😊
