You are literally my chemistry teacher at this point
WORD!
Facts
Seriously my teacher literally doesn't teach us, he just gives us assignments like bruh💀
@@divyanshiupadhyay513 my teacher only gives us exams 😭
@@ttravelingadventuress that's that bad, our teacher makes rarely exams
When you learn more from youtube that your university professor. Thank you so much for your awesome videos ❤️
facts
I can totally relate xD
U taking this shit in university while we taking this 8th grade
@@happymuslim6497 so what you doing here subscribing to him and to khan academy?
@@happymuslim6497 YOUR bad muslim
ive come to a conclusion that our lessons are dragged out on purpose so that the teachers can make money. BUT YOU MR TH-camR ARE A LEGEND U ARE LITERALLY SIMPLIFYING EVERYTHING MAKING IT SO TO THE POINT. MUCH LOVE MY BRO
Still coming back years later to say, you broke this down better than my professor could.
haha
I’m studying reactivity and electronegativity trends
I’m learning chemistry on my own
Best of luck boi! 👍❤️😊🌈🌈🐞🐝🎀🖊️📚❤️🧡💛💚💙
@@lightnox8388 I can’t, I don’t have much knowledge of chemistry dude
Same
damn mate sounds good, I'm studying biochemistry and molecular biology myself
Samee high-fives!
You're an amazing teacher. When I am not a broke grad student I am 100% donating to your channel.
I learned most of our lessons here, idk why I understand you more than our instructor. It seems like you're making everything easy to understand.
Bro this one guy is my chemistry, Computer Science and Math teacher lol
jesus this was more simple than i thought it was, thanks for making that clear :D
Bro this man is great. He's making me understand chemistry better :)
Welcome to TH-cam university where most students will graduate under this TH-camr instead of a university professor
Brother... you don't understand how much talent you got to make this look easy!!! I've gone through the entire physics series -- ALL A's. Now I'm learning chemistry/biology with you. You are hands down the greatest.
Thank you very much for these videos. I live in South Africa and we struggle because as an Afrikaans learner I don't get any classes in my home language anymore because of the government. Your videos have helped a lot. You explain much better than my teacher who also explains in English.
because of the government?
The government has plenty of wrongs, but it is not forcing Afrikaans speaking people to loose their basic human rights. South Africa is for ALL. There are plenty of schools that speak a variety of languages as a medium of teaching,, I would say more but lets celebrate and thank the organic chemistry tutor, no need to put out a false narrative, that has no facts nor substance.

Best teacher ever. Bc of you I don't even try that hard now on class BC I know I'll not understand from my University teacher. I have you so I just watch your videos before my exam starts and every single topic becomes easy and clear to me. Thank you so much. I'm really grateful to you. Wish you a happy and healthy life 😊❤
I'm learning this before class because I want a better understanding as I don't have a strong grasp of electronegativity, you single handily taught this!!!
When you turn to be my chemistry teacher and this channel turns to be my class more than my university, thanks bruh and keep it up🙏
THANKS TO THIS VIDEO I MIGHT ACTUALLY PASS MY TEST! Thanks for making this 😝
BRO you explained this so much clearer and easier than my chem teacher!
Can u post a video on calculation and application of electronegativity
I started to watch this channel for my computer doubts but now I use to watch all of your videos... Thank u My Organic Chemist😅
your really out here doing gods work with these videos
Guys please watch the ads as a thank you to him. This dude is the definition of amazing.
You always explain things very clearly, but for this video I have a question: How is the electronegativity value of each element being determined?
There is an electronegativity table
@@lxvkn Yes, but how is the value in the electronegativity table being determined?
@@YvonneZhou-m5tthat was what I'm going to ask 😅
Thanks a lot sir ...

__INDIA__..😄
Indiaa♥️♥️♥️
Who were seeing this before the exam
Me😂
My exam is the day after tomorrow🤪
I'm seeing this DURING an exam. Thanks Corona!
@@Coreyahno 😂😂same here
A year before the exam
Are you reading the periodic table or teaching something? How do you get/find/experiment the numbers for electronegativity?
do you have a quizlet for all ur material?
Professor Organic Chemistry Tutor, thank you for a beautiful explanation/Introduction of Electronegativity and Periodic Trends in AP/General Chemistry. The ability of an atom to attract to itself the electrons in a covalent bond is described in terms of electronegativity. The greater the electronegativity of an atom, the greater its affinity for bonding electrons. Electronegativity is always a positive number. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
Thank you so much man❤️you're doing such an amazing job 🔥God bless you.
You explained this so much cleverer than my Science Teacher... Thank You So So Much...💛 ^_*
well explained sir🥰
I believe the electronegativity follows the below order. Ne > F > O > N >= Ar > C > Kr > Cl > Br > S > Xe > Se ~ I ~ Rn> other elements..... Helium's EN is very difficult to predict. Its should be less than that of oxygen.
Noble Gases have exactly 0 electronegativity. They have a stable electron configuration with a full valence shell.
@@forlearning7352
No. They have relatively high electronegativity. XeF2 will be ionic if they have zero EN. They are reluctant to form bonds. However it doesn't mean that they have zero EN.
BIGGEST QUESTION I'VE GOT: HOW DO YOU FIND THE ELECTRONEGATIVITY VALUE OF EACH ATOM???!!!
Gabriel Tobing thanks a ton.,,
are you supposed to memorize them? ;-;
FruityBooty for real are you?
Its in periodic table
@@vipteumemashikyu4080
You're not gonna be given the periodic table in an exam hall, my dude.
Dude, you are doing an unbelievable service to the society . Bless you 😊
Thank you so much it really helps me to learn chemistry!
I'm writing tomorrow and I understood way better than my teacher, thank you so so much !!
Im in grade 9 studying chem by myself ur videos help me alot
It can be easily understood through this video
Love from India professor💞
Thank you for explaining it better than my instructor! God bless you; you are awesome!!!!
How do you find or calculate the electronegative values for the elements? Like 0.8, 1.5, and 1.9?
For example :NaCl
E.N of Na is 0.9 and that of Cl is 3.0.subtract it 3.0-0.9=1.9
@@robamatariq8485 can u plz elaborate it!!!
@@munawwarhussain3995 I have just given her the example that how can we calculate electronegativity difference.
@@robamatariq8485 I saw you explained how to find the electronegativity DIFFERENCE. Can you explain how we got those values? Like for Cl, its electronegativity is 3.2. How did you find it?
@@karthikdonepudi3767 you have to memorize electronegativity of the elements.
Thank you very much for this video! I did not understand it with the way my textbook explained it, but your explanation makes a lot more sense to me. 😁
Bro i thought u only had math, this is amazing
Greatest man to ever live❤️
I will get 90 plus in chemistry bcz of u hopefully😁😁
to everyone watching this to study for their chem test, good luck
I should have enrolled in TH-cam University😭😭 u teach better than my professors!!!
Thank you 😊 sooo much I thought I would never understand Electronegativity and intermolecular force but you made it Soo simple and understandable well Appreciated from Sierra Leone 🇸🇱🇸🇱🇸🇱
Can you please explain intermolecular force and intramolecular force 😢coz I still don't understand
@@kamomaretela1506 😂😂😂😭
@@kikijackson3303 😭😭😭😭😭🥺🤞help ...am serious
Literally, in every video of this channel, the comment section is mostly " Oh you are way better than my teacher" or " You are amazing"... and much more....... Well It is True XD,,,,,, WAY WAY WAY BETTER
My all confusions cleared after watching this video 😀
I DONT UNDER STAND ANYTHING ITS TO HARD I AM IN YEAR 3 AND I ALREADY NO WHAT ARE COVALENT BONDS AND IONIC BONDS AND CORDINATE COVALENT BONDS BUT I JUST WANT TO KNOW WHAT ELECTRO NEGA TIVITY IS
my guy you are a life saver
Does this guy tech some where or just in youtube??
If he does let me know his style of teaching is not random and he doesn’t confuse anyone.
He's rlly experienced I can tell. So he must have taught students at some point :).
@@Aalijah_Matyevna0:37 ofc he is!
In this videoooo best teacher ever
Ever nice videos.
I always recommend this channel to friends
Thank you so much sir☺️ for clearing my doubt..
What Did Fluorine say to the electron?
"Is it DESIRE, or is it LOVE that I'm feeling for you! "
Best of luck for y'all's chemistry tests!
If it is possible for you can you please cover some science university challenging topics with some more tough examples?
Hi
Hlo
Wait why is Cl+ > CL- Should it not be Cl+ < CL-
Didn't Cl+ lose a electron, pushing it back in the period, therforw less electronegative?
I’m thinking the same thing. Extremely confused right now.
Wow it's very informative with complete details
need this for school report!
Hi thank you so much for making these videos!❤️ I'm trying to learn how to calculate the difference when there is more than 2 different types of atoms like in KNO3 for exemple?
Thank you in advance!
Uh… doesn’t electronegativity only apply to elements? Not compounds?
Gawwd ,can't get enough of thanking ya mannn!!!
I love your videos♡ always very clear♡
You are good 👍 may God bless you😊😊
Thank you. You saved me.
l really enjoy this my tutor
I couldn't understand anyone lese but u thank u a lot dude
You are legendary
Good video collections.
Just a recomendation: volume is a bit too low. I don know if i have a way to increase it in this cell phone.
Wala akong pake tanga
Thank You Teachers
Well done, thanks
Thank you
i love this person
Ur explanation is nice sir
Where do you get this electronegativity number?
Most periodic tables have them. Mine does too. Usually they're under the element.
Andrej Nikolov what if it doesn’t how do you find it?
@@acelia_ tq
th-cam.com/video/lXuHTtdYxPs/w-d-xo.html
Thank you so much
very helpful video,thank you
‘Fluorine really wants an electron, if it’s placed next to an electron, it will acquire it.’ So passive aggressive and threatening at the same time
I'mma tell my GF: "I am Fluorine and you are my electron, that means I love you and have a strong desire for you!"
LMFAO TF
But what if she says she is Sodium and don't have a desire for u lmao
@@900q8 haha xd
She pulls an Uno Reverse Card on me!!
@@900q8 did you see my other comment?
@@Matt-sc6gg yes kid this kid wrote 2 comments lol
Hi, if the first two pair of elements (Cr and As) have an electronegativity difference of 0.4, are they nonpolar covalents? If so, then I am confused, because I thought covalents could only be non-metals bonded to non-metals.
It is very useful class
How did Pauling calculate the electro negativity value of one atom??????
Thanks
How about HCN? It has three elements. How can I solve its electronegativity difference?
The best of the best 🎉
Thank you so much, this was really helpful to me.
Thanks! Very helpful.
ur voice sounds so good
hits better when it's 1.5x speed
best teacher
I JUST HAVE ONE QUESTION. Is there a solution or formula to get the electronegativity of an element or was it already given and doesn't need to solve?
It’s in certain periodic tables
You have a nice voice
😊 good idea
Pls could you give an explanation on the dipole moment of Boron trifluoride
Thank you
Thanks.
Need a trick to learn this value
What do u mean by less and more electronegativity.....
Thanks a ton!😊
Which is more electronegative, N or Cl?
cl
