11:19 fluorine should be the smallest anion .
But in question ask first most and then least
Yes...but y is there no such option....
Lecture starts at 4:02
11:11 The answer should be B) LiF and LiI ....(as LiF is even less Covalent than LiCl)... and further they haven't asked 'respectively' ...
Yes I agree with ur answer
at 29:35 CsCl is most ionic according to fajan's rule, but why does it have lowest melting point amongst them.
Mp depends more on Lattice energy
@@gedumlego3814 ok
Same doubt but clear Ho gym
It depends on lattice e
Because it's data fact in some cases fajan rule works in some cases lattice enthalpy case works example if we talk in any metal halides both lattice enthalpy and fajan rule works but if we take talk halide of alkay metal particular with cl br and I only lattice enthalpy works so it's data
35:20 but experimental data shows that the melting point of znco3 is almost double than that of mgco3
Right bro........i am also thinking about that....
thermal stability does not mean higher melting point.... it means which will dissociate faster using less heat energy
Bro you are right actually. ZnCO3 is thermally more stable. ZnCO3 is more ionic as Zn2+ ion is larger than Mg2+ ion. Thermal stability is directly proportional to ionic character.
YOU ARE GOD OF CHEMISTRY AND GOD OF HUMOUR😂😂
Please sir have a PYQ session on Periodic table chapter and this also🙏
Some pyqs have been discussed in dpp😊
@@anjanasingh9562 what is PYQ???
@@twilightzer1147 previous year questions
@@noname-ug1jo yeah, got it
Thank you so much. 🙏
Unacademy jee is the very best channel
35:20 ZnCO3 is thermally more stable than MgCO3 because polarising action of Zn2+ with 18-electron configuration on the anion is larger than that of Mg2+ with a noble-gas electron configuration and of same size and charge. 😢
Plz post the notes of lecture 4 of chemical bonding..
Here it is = 4:02
SIR LECTURE-4 CHEMICAL BONDING NOTES IS NOT UPDATED YET.
thank you sir....your dpp is very helpful...
Sir last class ka notes abhi tak upload nhi hua h
Sir aap decipline vala vedio delete kar diye kya

Actually school meh itna tezz pdha rhe hei na...ek chap khatam hua hi ki dusra start ..grasp krneka time hi nai milta.. Questions kab banayenge yaar. Aur inhe nb bhi complete chahiye. WOWW
11:22 LiF is more ionic than LiCl
In option C that was LiI NOT LiF. And as fazan's rule we know LiI is more covalent than LiCl
Thank you sir for your great support to us and giving your precious time 🙏🙏🙏
Superb🤩🤩🤩😎😎😎
sir 2019 METALLURGY WHERE ??????????? HOW TO PREPARE FOR 2020 METALLURY IS NOT THERE
pagal
Sr Lewis dot structure of SO2Cl2 me oxygen double bond kyu banata hai???.
Cause oxygen needs 2 electron to attain noble gas Configuration.
ZnCO3 is more stable then MgCO3
Sir at 28:41,NaCl to sabse jyada covalent he,tab for uski lattice energy sabse high kaise
aare bhai nacl mein ionic character jyada hai.
dhyaan kaha hai ?
@@JITN0W according to fazan's rule .lesser the size of cation more the covalent nature. So. Na+ has more covalent nature then Cs+ .... therefore more the covalent character lesser the MP ..🤨🤨🤨🤨
@@poojaprasad8573 ionic radius se answer hoga...smaller the size greater the bond energy stronger the bond
@@mdsabilsarfaraz7685 toh fir sir uske bad vale question meh fajan rule kyu use kiya ....tab size wali baat kyu nahi ki?
15:20
Sir sab hum apne se hi krlete to yaha is platform pr kyu aate....😁😁
But N can't have a covalency of 6, so structure#3 is not that stable. Am I right?
isn't that why it has -ve charge?
how to join in unacademy....
You are good teacher in the chemistry faculty please develop the content
Sir, are these lectures enough to crack JEE MAINS as well as JEE ADVANCED ??
Please respond sir, I am really in doubt 😞
Jee mains ke liye hai
@@narayanguptashorts7610 advanced k liye b h
I think for mains level only 🤔
Sir chem mera phobia till now
Sir solomons and fryle book ke soln series continue kriye plsss
I think most covalent halide of li is Lil but least is LiF
LiCl is not least covalent
Please explain??
You have to choose from the given options only ...which suits best .. anyways LiF is more ionic than LiCl u are right.
Sir.... Jab aapp khajoor bolte ho to bahot achha lagta h 🙏🙏

thank you, sir

sir please don't ask to share the video
agar mai share karunga to or bhi log video ko dekhenge

@@divyanshsah8472 bhai duniya me jina hai to aise hi karna padega
😂😂😂mai to krti hu recommend khul ke
Maza aa gaya
Thanks sr
Sir , I think you made a mistake in 1 question.
ZnCO3 is supposed to be more stable than MgCO3 as polarising power of Zn2+ is more than that of Mg2+ . So lattice energy of ZnCO3 will be more than that of MgCO3 ,hence ZnCO3 is thermally more stable
yes you are true
Greater the polarising power greater the covalent character so u r wrong
Ha bhai Mera bhi yahi doubt tha😊😊
Excellent lecture.
34:10 😂😂
pura containt last year.. sir km se km question to change kr do.. yhn tk ki order of question bhi same h😯😯
Krapya karke 12th wale apna gyan na de aur 12th ki class dekhe. 11th walo ko padne de kyunki 11th wale ye question first time kar rahe hai

Sir don't teach like this there are many students there whose teachers teaches them in the same manner. In this we aren't able to study properly.
