thanks mam It helps us a lot . when i started watching lecture i was writing my doubts which is thought i will ask in online class but as further i keep on watching video i am left with 0 doubts . zero doubts thanks again mam and sir . mam i will request u to plz make a short video on NMR . i will help us a lot.😇😇😶
Mam ,I think You actually interchanged Shape and Geometry unknowingly.. I guess Shape includes lone pair repulsions whereas Geometry does not. Please correct me if I am wrong . @2:28:40 Rest the lecture was amazing I got my concept crystal clear through this . Thanku for this masterpiece series.
Yes vivek, Lone pair is not considered in shape but due to lone pair - lone pair repulsions, shape will change …Hence lp effect shape but we have to hide this while observing shape….
Mam bohut hi acha se samjh me aya +point it is in one with numerical which help us lot in exam time Only request is plz give the notes of this lecture 🙏
mam I think the correct order of electron gain enthalpy is S> Se>Te>O(given data fron the table is -200>-195>-190>-141..................if I am not wrong
Thanks ma'am for your videos to make our ENGEERING CHEMISTRY strong... Your way of explaining things in depth and with proper details is so appreciating....And also thanks to Manish sir that we reaches to you.... SYED HAMID -21462 (CSE)
Ma'am, do this module Consists: "Intro to reactions invloving substitution (electrophilic & nucleophilic substitution), addition, elimination. Synthesis of some commonly Used drug molecule.
Effective nuclear charge, penetration of orbitals, variations of s, p, d and f orbital energies of atoms in the periodic table, electronic configurations, atomic and ionic sizes, ionization energies, electron affinity and electronegativity, polarizability, oxidation states, coordination numbers and geometries, hard soft acids and bases, molecular geometries
Mam at 45:50 third orbit ke " D" Orbital me jo 2 electron hai uske liye to value 2*1 lenge.kyuki d and f ka value n-1 ke liye to 1 hota hai.aur 0.85 to s and p orbital ke liye sirf hota hai.Aapne 0.85 se hi multiply kr diya hai. Simillarly mam aapne bromine case 50:10 me bhi yhi kr diya hai.Please reply mam. As early as possible. Ya fir mai hi galat hu???? Doubt clear kr dijiye.
Ma'am abhi module 4 mein bhi 2 topic rahte Hain mere according 1 corrosion de Rakha Hai aur ek metallurgy and ellingham diagram agar Un donon per Bhi ek ek video dal dete toh meri help Ho jati Actually Mera 9 tarikh ko paper hai sessional aur aap ke module 4 Mein yah do topic nahin

Good luck and all the best😊
@@ChemRankers Pass ho gaya mam . thank you so much . your Bihari accent is soo cuteee❣
Congratulations beta….I am soo happy for you😃
Aree bhayi 😂😂😂😂
Periodic properties ka pura concept bahut achhe se samjhane ke liye thank you mam 😊
Thanks Amir…
Bahut achhe se samjh me aata h aapki pura leacture.
Thnxx so much ma'am🙏🙏👍.
Thanks Atul….
Good evening ma'am.
Ma'am Jitna aapko thanks 🙏 abhi bolu to sayad wo bhi Kam padega have got 95/100 marks in chemistry and also this number is college topper.🎉🎉🎉🎉🎉
So a lot of thanks 🙏
I m so glad to hear that😃
The way u teach is so unique and easy to understand each and every topic, thanku so much mem for this vedio☺
Thankyou so much Shreya…
One of the milestone channel for chemistry😊
u really work hard for me all students.tankq for this.and i really proud of my sir who suggest me ur lacture 👍
Thankyou Saurabh 🙂
We are so thankful to you 🙏🌻mam🌻🙏 as you are spending your precious time to impart your knowledge. So that we must be better in our studies.✍️✍️
Thank you very much Shubham... Thanks a lot...
Madam sachme ap bohot achhe se samjhati hain and also all topic cover karti hain...
Aap aisei aur bhi video deti rahe....😊
Thank You mam, & MJ Sir, You made this easy to understand.
Thanks dear😀
Mam aap video banaeye ki hm engineers how to explore in our college life
Ok... I will... 👍
Ma'am i am just so mesmerised with ur teaching ....
I really like the way how u explain each and every detail.....
Thankyou so much 🙂😀
Maam plzzz stop mt kro ye series aap osm teacher ho plzz continue maam sem 2 aa gya h aur khi v lec nhi h plzzzzzz maam continue the series
Thank you very much.... But syllabus is completed..watch complete playlist.... Still we will continue very soon....
Thank u mam bahuat acha se samjhe me aa jata hai 💯
👍
😀
This video is really helpful to me for clear my concept about periodic properties . ✌️✌️✌️
Great👍
Mam you did one mistake in Electron affinity trens in chalcogen family. S>se>te>po>O
After sheilding nucleus kitna eff h wo h zeff
X attraction me se y repulsion minus ke bad jo v nucleus ke pass eff h wo h z eff
Zeff = z-sigma
Sigma =slatter screening constant
1:20 ,n=no. Of shell
Metal try to loose one electron
Non metal try to gain one electron
IA mtlb electron affinity
Zeff jayada mtlb nucleus hold kr sakta h
Second electron gain enthalpy always positive
Electron gain enthalpy
Cl>F>br>Idown the group dec krti
Same for oxy and sulphur
Koi Cation kiss anion ko kitna jayada polarize kr sakta h wo polarizing power koi anion kitna jayada polarize ho jata h wo polarizability
More charge more covalent less charge high ionic nature
1:58:07check polarizing power it depends on charge and size
MN ke bad pairing suru ho jati h MN have highest oxidation state
BF3 trigonal planner
Hard acid plus charge jayada ya size chota
HI is more acidic than HF
Mam bahut achhe se sumjh mai aaya 💯💯💯💯💯
Thank you so much Mam
Most welcome Satish…
thanks mam It helps us a lot . when i started watching lecture i was writing my doubts which is thought i will ask in online class but as further i keep on watching video i am left with 0 doubts . zero doubts thanks again mam and sir . mam i will request u to plz make a short video on NMR . i will help us a lot.😇😇😶

Thank you mam
My all doubt is to be clear in periodic properties for this video thanks for to state an exception case and thanks for manish sir 😊😊
Welcome shivam..
Mam ,I think You actually interchanged Shape and Geometry unknowingly..
I guess Shape includes lone pair repulsions whereas Geometry does not. Please correct me if I am wrong . @2:28:40

@@ChemRankers well deserved 😊
Mam important questions mil sakta hai kya?
mam 1.40.00 ma O ka EA value -141ha and Se=-195, Te=-190 so EA ka order asa hona chiyea S>Se>Te>O
Ma'am notes mil jata to bohot accha hota
