Thank you
Correct answer is option D. Explanation is correct but answer is marked c by mistake at the end of the video
hurray🎉 I solved it in one go without knowing the formula of ethylene glycol
good question
Sir last wala question samjh nahi aaya ek baar fir se samjha denge please
Thanku sir I was confused in a and b option..
Very helpful please april attempt 🙏
Option D is correct
yes
yes
Nice qustion
Thanks sir Ji ❤
Thanks sir ji❤
8:34 D?
sir is question ke liye toh Glyoxime ka structure bhi yaad rakhna padega?
yes you need to know structure of dmg and the complex
Thank you sir
Question pe used acid bola hai matlab jo h2so4 use hua hai usee neutralise karne mein 30ml of 0.25 naoh lagega ..
yes
Sir if statement says The strength of point charge ligands can be explained by crystal field theory. This is true or false B.
No. See in ncert [from the assumptions that the ligands are point charges, it follows that anionic ligands should exert the greatest splitting effect. The anionic ligands actually are found at the low end of the spectrochemical series.] Assuming ligand to be point charge is the part of limitation.
Good 🎉
Ye konsa chp se hai sir
Salt analysis and coordination compounds mixed question.
Very very helpful sir... Thank you, 🥺🥺
Why you add ate charge on central atom is positive
consider it as K2[MnO4] so it is a complex anion ie. MnO42-. For complex anion we add ate after central metal name.
Thanks @@neonjee
Very easy way Tq
lost for words , never seen anyone go this indepth , all concepts crystal clear
❤thank you sir bhut help hori h Please sabhi shift ka jaldi le aayiye
NaoH aur H2so4 ka titration q Kiya kya vo ye janne keliye kiya ki kitna Bacha hai H2so4 Agar haan to fir Aapne equavalent of nh3 and NaoH equal to total equavalent used H2so4 liya hai kya last mein ?
in last line it is : meq of NH3 + meq of NaOH = total meq of H2SO4
❤❤❤thank you sir sare concept clear hore h but sir please jaldi 1feb shift 2 and april k bhi jaldi krva do
Sir option one is major product so it is more correct
could you explain in detail?
Sir april ke solution le aayiye plz...!
Yes on dilution molar conductivity increases,because ions are free to move.same knowledge we can apply here.on dilution more number of ions,so I is more.
Sir plz make speedy solution in 70-90 minutes for 30 questions of each shift
good❤
Sir January k toh aapne bna di h Ab April k pahle bna do please
Sir instead of these small videos, make a 1 hr video and discuss all 30 ques of a particular shift speedly ..... We have very few days left now, i request you to upload all 2024 shifts pyq ASAP
Sir instead of these small videos, make a 1 hr video and discuss all 30 ques of a particular shift speedly ..... We have very few days left now, i request you to upload all 2024 shifts pyq ASAP
making one video of an hour for all 30 questions will be like solving questions at exam speed. While it may be useful for many ... i will not be able to cover the solutions in as much details as i would like to. There are other great channels which do solutions in one video, see those, for eg. try checking out dexterchem by Rastogi Sir.

Sir please jaldi Karva do Test analysis m bhut help multi h sir please
Cation lithium is large size know compared to fluorine??!! 5:40..
by small cation we don't mean smaller than anion, it is that smaller the cation more the covalent character or higher the charge density on cation higher the covalent character. It's a comparison between two cations not cation and anion.
0:20 opt 4 is correct
Sir this reaction is given in which chapter in ncert
see p block 2 under properties of ozone
Sir jaldi upload Kar dijiye please bhut help hori h
Easy question ❤
Thanks🎉
Sir ye electrochemistry ka concept hai on dilution the molar conductivity increases
Sir aap bhut deep m shamjate ho Sab shamj aata h ❤❤❤ Sir please can you create pyqs revision series it going to very helpful sir If you start pleSe first lecture is ionic equilibrim
Easy as shit
Sir bache hue pyqs bhi jaldi krva diyije please
sure
Sahi hai sir ikdum badhiya
d block cation have more polarizing power than any s block element cation and in d block polarizing power depends onn z effective that 3d<4d<5d ki polarizing power more polarizing power means more convalent nature
Thank you sirji
We can also do it by pngc( pseudo noble gas config) for group 11 and group 12 elements like cu,ag,au,zn,cd,hg!!!! They have most covalent character!!!
