Sir , man behind the video is amazing ! Loved the thumbnail :D Sab video lectures me se aapki efficiency sabse zyada badhiya hai , quality : speed is way too perfect !
I did some research and found that it will stop the reduction at aldehyde if the temperature is lesser than -70 degrees celsius. So basically the question has: 1. Lack of assertion of amount of reactants 2. Ambiguous details of temperature where the choice of temperature is critical 3. A poorly framed context.

Everything was good but Sir, the soubilty of SODIUM IODIDE is more than Lithium iodide since it has more ionic character. (Li.I as per fajans rule posses Covalent character so it is comparatively less soluble in polar solvent like water)
Sir i have a doubt in inorganic chemistry. WHY BeO has higher melting point than NaCl? Acc. to fajan's rules NaCl should be more ionic and have high melting point. But this is opposite. Please reply soon.
acc to fajan if you considered plarizibility oxygen is more electronegative and small size so it will not share it electron as compare to chlorine have more size oo cl will shitft towards na more
sir "how to compare solubilities" ke video ke trick kya hum gp1 &gp2 dono ke liye same apply kar sakte hai? plz plz plz clear my doubt bcz Maine CO32- ,Cl- ke liye dono gps ka order reverse pada hai. plz help me.
Sir u said that LiI has more solubility than NaI bt I think since both the cations have similar charge and size of Li ions is smaller so acc..to Fajan's rule LiI shoud be more covalent in nature hance it should be less soluble than NaI...plz do correct if i am wrong.
sir top to bottom to atomic radius increse krtaa hai to ionic potential of mgoh2 kam hogi to solublity bhi kam hogii and ionic potential =charge by radius hota hai and aap charge by size se solve krre ho sir qki size ght ta hai and radius bdhta hai size se q sir radius se solve q nhi ???
Sir for large anion solubility decreases down the group, But then why for group 1 carbonates solubility increases from LiCO3 to CsCO3? Carbonate is large anion only.
Sir according to the concept of like dissolve in like , ionic compound dissolve in ionic solvent and covalent compounds dissolve in covalent ..... organic compounds have covalent bonds so it's dissolve in organic solvent ....sir is it true ?
sir between LiI , NaI , KI , polarising power of KI is less hence its solubility should be more,, Sir i m really confused when to apply which rule.. plzz help
Sir I want to crack Jee main 2018 and want to get in Nsit Delhi . Can u suggest me some tips and books to crack Jee main with good score . I've weak 11th base .and yet I am in 12th.
Sir plz suggest how to do qualitative analysis. Because jee advance always ask two or more questions from that chapter, i have studied it but still I'm unable to solve jee advance questions. So plz help!
could u upload thermal stability of allotropes and thermal stability of all compounds like hydroxides, hydrides, carbonates, bi carbonates, suphates , nitrates, halides ... ete caparisons
thanks sir for the video. I have a question . I read it in my coaching notes that li2so4 is least soluble sulphate in 1a group. sir, kindly explain why is it so? (as the solubility should decrease down the group. )
sir can u upload a video on how to study for mains nd advance by a repeater...and if the same candidate has joined another college for preventing a year loss ..then how can he / she manage time..
sir plz make a video on the organic reagents ex oxidizing / reducing etc... and how they react in the presence of other groups for ex if lialh4 is taken we all know that it is good R.A.and reduces aldehyde /ketones to enol and alcohol BUT WHAT WILL HAPPEN IF THEIR IS ANOTHERGROUP PRESENT IN SAME COMPOUND SUCH AS CYNIDE /ETHER/ ESTER THEN LIALH4 WILL REACT WITH WHOM 1ST ???
Excellent explanation
Thank you Sir❤️🙏
Thank you very very very much
Thank you sir
Amazing😍😍👍👍👍
Full Video 👌
thank you sir for such a time saving and clear explanation
You are most welcome
really very helpful video
Even today explains the concepts very aptly
awesome video
Good explaination
Thnkuu so much sir❤️
Thank you soo musch
u r gr8 Sir hats off

Sir , man behind the video is amazing ! Loved the thumbnail :D
Sab video lectures me se aapki efficiency sabse zyada badhiya hai , quality : speed is way too perfect !
Thats video i finding for 2 hours
aap great ho
tnx sir..hlp to cler my all doubts😀
Well explain sir always helpful in solving conceptul doubt
Amazingggg sirrrrr thankuuuuu
please do not stop uploading videos
we appreciate your hard work
This is what I was looking for .Thank you 😀
Wow Sir , These 10 min. Efficiently Cleared my all confusion Here.
Thanks A Lot :)
Most welcome! keep watching & shower your love & support for more such lectures @also keep share with all your friends.🤞
sir why we didn't you the anionic character concept which you told to compare solubility?
Carbonate ka size bada hai so
Li2CO3 > Na2CO3 for solubility but it is the opposite why ??
Sir kya polarizibility charge aur size dono ke directly proportional hoga..
Is OH considered a large anion in comparison to Mg and Li??
solubility trend for alkali metal chlorides?
💜
Sir how can we compare ki kaun si anion ki size jada badi ya comparable kam badi h
I am highly grateful that after so much struggle to understand this i found ur video
thank u so much sir,i need such type of video
Sir what is the answer of DIBAL H question in jee main 2017? it has two possibilities
Any Time Padhai Academy Sir Dibal H reduces COOH group also
But it's not given in limited quantities also(like no mentions of amount of equivalents of DIBAL-H)
Twarit Waikar Thats exactly my doubt
So I assume this question can be challenged?
I did some research and found that it will stop the reduction at aldehyde if the temperature is lesser than -70 degrees celsius. So basically the question has:
1. Lack of assertion of amount of reactants
2. Ambiguous details of temperature where the choice of temperature is critical
3. A poorly framed context.

Your videos are to the point, thanks
Everything was good but Sir, the soubilty of SODIUM IODIDE is more than Lithium iodide since it has more ionic character. (Li.I as per fajans rule posses Covalent character so it is comparatively less soluble in polar solvent like water)
Bhai aap tou jd lee ka pura bata rahe ho.. Aapna concept batao...
Sir i have a doubt in inorganic chemistry. WHY BeO has higher melting point than NaCl? Acc. to fajan's rules NaCl should be more ionic and have high melting point. But this is opposite. Please reply soon.
acc to fajan if you considered plarizibility oxygen is more electronegative and small size so it will not share it electron as compare to chlorine have more size oo cl will shitft towards na more
so Beo have more ionic chracter
None could elucidate this concept so crystal clearly...Wow!!!
ATP is the last hope when all resources fade.......
sir "how to compare solubilities" ke video ke trick kya hum gp1 &gp2 dono ke liye same apply kar sakte hai? plz plz plz clear my doubt bcz Maine CO32- ,Cl- ke liye dono gps ka order reverse pada hai. plz help me.
Always behind your videos....
Sir u said that LiI has more solubility than NaI bt I think since both the cations have similar charge and size of Li ions is smaller so acc..to Fajan's rule LiI shoud be more covalent in nature hance it should be less soluble than NaI...plz do correct if i am wrong.
in case of big ion solubility decreases down the group
fajan rule not applicable here
Great job sir...
some video don't save .
why???
Now i call this el-classico explanation.. 😊😊
Hi
god bless u sir
sir top to bottom to atomic radius increse krtaa hai to ionic potential of mgoh2 kam hogi to solublity bhi kam hogii and ionic potential =charge by radius hota hai and aap charge by size se solve krre ho sir qki size ght ta hai and radius bdhta hai size se q sir radius se solve q nhi
???
But for Alkali metals caesium sulphate is more soluble than lithium sulphate why the logic fails here?
Explaination was the best
Before this video i was trying to learn the orders but now no need of ratta
Concept is cleared
Thanks a lot sir
❤ ur videos sir
sir how to stop masturbation and watching porn
I'm a student and my life is destroying
I've tried everything but nothing is working
sir please help
Any Time Padhai Academy sir please tell how masturbation affects study... please sir..you can save my career
wtf!!!😂😂😂😂
cool down bro
Bhai TV aur smart phone use Na kar for only 10 days
don't overdo it , if you'll overdo then it'll affect ,else there is no such great effect as long as you are able to study
sir please upload the video of questions on solubility product
Sir thank u sir .you made my concepts crystal clear ....keep doing it
thanku sir god bless u
Sir for large anion solubility decreases down the group, But then why for group 1 carbonates solubility increases from LiCO3 to CsCO3? Carbonate is large anion only.
There is a exception for carbonates bicarbonates and oxalates
thank you :)
Best video I have ever seen on this topic. Thanx sir..
Salvation of NaCl is an endothermic process , so is it not therodynamically fusible?
*MgCl2 And BaCl2 ke case mein kya hoga* anybody tell plzzzzzzz
Sir i like your videos before watching videos .u r amazing sir.Keep it up
Sir can you tell which anions should be considered large because s block metals are also large
What About Thermal Stability of Mg(OH)2 And Ba(OH)2?Is Ba(OH)2 thermaly More Stable Due to More Ionic Character and hence Better Lattice?
Thanxx sir for making clear concept videos ....!! Thanxx a lot..!!
atp is best
when is part 4comig???
Sir if the two ions of a salt are of comparable sizes then will the solubility be more or less
thanks sir u have cleared my all confusion that I was having for 2 years
thank u so much sir
Sir chemical kinetics ke question bhi question bhi lgwa degiyega please sir mera chapter weak hai please
Great concept sir every year question based on this concept asked in every competitive exam👍👍👍
sir please upload a video on super trick of any physical orgabic properties of compounds its difficult to learn it from ncert as it is very lengthy
Sir according to the concept of like dissolve in like , ionic compound dissolve in ionic solvent and covalent compounds dissolve in covalent ..... organic compounds have covalent bonds so it's dissolve in organic solvent ....sir is it true ?
Sooo Many exceptions...Why doesn't one rule work in chemistry????????Whyyyyyyy.
Same as life
sir can you please make a video on electrochemistry
it would be perfect video if you would have mentioned what is examples of large size anion . otherwise it helped be a lot
sir ur teaching is just AWESOME
sir i was not able to perform well in mains...i am giving wbjee...give some tips...
sir between LiI , NaI , KI , polarising power of KI is less hence its solubility should be more,, Sir i m really confused when to apply which rule.. plzz help
brilliantt sirr...u cleared all my concepts..thank u very much sirr..and keep making videos for other chapters too!!
Your trick not applicable for Group 1 Sulphates.
Bal
sir IA gp k metal carbonates ki solubility Inc hogi ya dec ??
Sir can u upload a video on Imp Concepts of Mole topic it's very confusing

sir according to jd lee NaI has more solubility than LiI
electro chemistry ke aur videos uplode kijiye for neet plz sir ....
sir thermal decomposition par video banao na.
sir please make a video for NDA entrance exam 23 April for questions ticking strategy
sir plz make a video on the organic reagents ex oxidizing / reducing etc... and how they react in the presence of other groups for ex if lialh4 is taken we all know that it is good R.A.and reduces aldehyde /ketones to enol and alcohol BUT WHAT WILL HAPPEN IF THEIR IS ANOTHERGROUP PRESENT IN SAME COMPOUND SUCH AS CYNIDE /ETHER/ ESTER THEN LIALH4 WILL REACT WITH WHOM 1ST ???
