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 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 🙏
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.
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 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
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.

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…
Nice lecture hai ma'am pura Cristal clear samajh aaya.please ma'am 2nd semester ka bhi lecture upload kigiye.i request to you...
All modules are already uploaded….total 7 modules in AKU syllabus…
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...
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 🙂😀
Bahut achhe se samjh me aata h aapki pura leacture.
Thnxx so much ma'am🙏🙏👍.
Thanks Atul….
This video is really helpful to me for clear my concept about periodic properties . ✌️✌️✌️
Great👍
Madam sachme ap bohot achhe se samjhati hain and also all topic cover karti hain...
Aap aisei aur bhi video deti rahe....😊

Thanks dear😀
Mam aap video banaeye ki hm engineers how to explore in our college life
Ok... I will... 👍
We can't thankyou enough for all your efforts, sacrifices, love and care.🙏🙏
Just work hard and achieve your goal...
Thank u mam your video is very important to our syllabus and your lecture is very easy to understand every concepts and doubts are clear..
Thank u mam bahuat acha se samjhe me aa jata hai 💯
👍
😀
thankyou ma'am for this lecture which concept you teach in this lecture is very easy to understand and the way of your teaching is best
Thankyou 🙂
Thank you so much mam your all one shot videos are very helpful and very important again thank you mam 🙏🏻🙏🏻🙏🏻🙏🏻
Good evening ma'am.

So a lot of thanks 🙏
I m so glad to hear that😃
Thank you mam, please share mole concept link. I have checked your channel but I didn't find that. Love the way you teach ❤❤❤
Thankyou ma'am bahut achhe se samjh jate hai easy se
Awesome class mam I understood all thing and most of beautiful thing is that first time I understand the numerical 😊
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..
Thank you mam for this video.it is very helpful to understand periodic table and property.
Welcome Abhishek…
Thanks ma'm for this amazing video.it's really helpful for me to cover module5.😊

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....
I love your lectures ma'am ❤️...Itz highly recommended for engineering students 🙏
Mam bahut achhe se sumjh mai aaya 💯💯💯💯💯

This vidio is helpful for me .
Becz z-effective ,shielding effect concept is clear in eassy way thanks mam🙏🙏
Glad to hear that....Thanks Shyam...
The best teacher ever
Thanku mam ..
Mam you did one mistake in Electron affinity trens in chalcogen family. S>se>te>po>O
finally got the perfect playlist for engineering chemistry🥰
but its too late now🥲
thank you very much ma`am🤧🙌
Great explanation mam 🔥🔥🔥
Thank you so much Mam
for this wholesome Playlist
Thank you so muchhhhh Mam
bahut helpful hai exam ke liye 🤍
Thanku so much mayam 😊😊....this is very amazing lecture
Thankyou so much 😊
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
Yadi aap na hoti to Mai raton rat 5 double kaise cover karta. Thanks a lot didi
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.😇😇😶
Thankyou so much Abhishek…
Thanks you so much mam and MJ sir... each and every concepts are clear...❤️
Welcome Ashish…
Mam you so good in your teaching 👍👍👍👍👍😊😊😊🥳🥳🥳🥳🥳
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 🙏
Thanks mam for helping us and also

@@ChemRankers well deserved 😊
Ma'am, do this module Consists: "Intro to reactions invloving substitution (electrophilic & nucleophilic substitution), addition, elimination.

Very very helpful..
Thanks for this good video mam

Tq for explination
Thank you mam 🙏 ☺️
16:57 Wont Feff also include electron-electron repulsion ??
Thankyou mam and sir for this amazing lecture. Mam i wanted to know which books you reffered while preparing this lecture?
Content is taken from multiple books Shivraj to cover each and every concept…
Thanks mam
Welcome ☺️
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
Thnku didi 😊
Baki sab.. Ban ban ban ban ...😂 Thankyou for amezing contribution 🩵🙏
Ma'am notes mil jata to bohot accha hota
