This can't be stressed enough but thank you for taking the time to make these videos to teach these concepts. To say this it is a noble deed is an understatement.
Thank you so much :DDD. Thanks to you, I save so much time and energy. Instead of spending an hour trying to understand the concept in my textbook and crying, I can just get it over within 10 minutes. I will make sure to mention you in my graduation speech :)))
Professor Organic Chemistry Tutor, thank you for an excellent analysis of Bond Polarity, Electronegativity and Dipole Moment in AP/General Chemistry. Once again, the practice problems are the best way to learn this material from start to finish. Problem solving improves students/non-students understanding of the material. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
Your explanation is very outstanding compared to all tutors. I got more help from your videos on maths, physics and chemistry. You are very talented and brilliant.. Thankyou very much..
How do you know whether molecules are polar or nonpolar overall? An explanation of how the arrows magically cancel (or don't cancel) would be greatly appreciated!
@Jessica Whittingham wait so by adding up the vectors, you mean just subtracting the electronegativity of each atom and seeing whether or not it equals 0? Otherwise, thanks so much i was rlly struggling in class today lol. The only part that gets me is the word choice for "canceling" or "not canceling" arrows. I get which way they face though thanks to you lol. Thanks a bunch! :} (btw it would be appreciated if you used an example as well :) )
Let's be real here, the professors don't even allow us to have these values in class. I love these videos but organic simply isn't fun because the majority of professors can't teach it properly to begin with. This is just my opinion.
Hey! Thanks for the video, ITS very helpful; just have one question. In the book im using (and what my teacher taught, when the electronegativity difference=0 the bond is nonpolar. Any value in the range 0
Hey guys, a bit confused. For electronegativity difference for polar molecules, does it include 0.5? I thought my teacher said all values greater than 0.4 for EN are polar, so just gotta make sure because the vid said >0.5
Great video but I still don't understand the arrow part. How do you know if you cancel or don't cancel. I never took a physics class so I am completely lost with that part. Can you explain the arrow part in simpler terms. Is there like a trick or something?
Yo you didn't even mention the lone pair that allows the H20 molecule to be bent causing the dipole moment, without this molecule seems symmetrical and the dipoles would cancel, seems like a crucial concept
Actually Christina...for the elements..they already have an original constant electro negativity value...so when it involves two elements together...and asked to get there net electro negativity charge...d subtract one with highest EN value from the smaller one bearing in mind the whether is gonna b higher than or equal to 0.5(i.e being polar ) or Less than 0.5(i.e being non-polar)..😊 Ah hope this helps😊
Kelvin Fadojutimi Try using the trend on the periodic table. Electronegativity increases as you go across the period from left to right. It also increases as you go up a group from bottom to top. Keep in mind this excludes the noble gas and F is the most electronegative atom in the periodic table.
@@ChemSimplified how can i find out if a two atom molecule is polar/non polar then? say the atoms aren't the same cuz then it would be non polar straight away
@@suryajandhyala You need the electronegativity values to figure that out. There's no way you can figure out if the molecule is polar or not without the values. What I meant in my earlier comment was that you can use the periodic trend to figure out which atom is delta + and which is delta -.
brilliant however you failed to indicate the type of bond at the border, example if the δEN is = to 0.5 like in the case of CI therefor the non polar covalent bonds electronegativity have a δEN less than or equal to 0.5 not just less than 0.5
Just know the periodic trend for electronegativity. I forget on the spot, but I think that electronegativity increases as it goes from left to right on the periodic table, while it decreases as it goes down. Just compare locations of the elements and it should help out.
At 1st u mentioned that if the EN is lesser than .5 then the bond is non polar... If thats the case, then hows O-F contains polar bond if the EN is 0.5? Plz sir, respond to my question asap🙏
Samina Yeasmeen you answered your own question. It’s not less than 0.5, so it is a polar covalent bond. 0.5 is not less than 0.5, it is 0.5 therefore polar.

suddenly chem makes SO MUCH SENSE TO ME NOW
This guy has the best videos on maths and the respective sciences.
The amount of help this vid did can't be described in words I will be grateful for you for life
You such a blessing to me.
Thank you so, so much man. You’re saving my GPA in 10 minutes ❤️❤️
man u be saving my life by giving all the topics i missed in detail god bless
Holy moly, this channel is gold. You got a new fan in Norway ;)
Good job though, really.
you’re making me survive chemistry atp

Ethiopia sil roche gebaw lol
get this man into HARVARD TEACHING CUZ MAAAAAAAAAN THIS GUYYYYYY IS AMAZIIIIIIIIIIIIIIIIIIIIING CUZ OF HIM I GOT A A* IN CHEM
IGCSE?
You must earn the world best tutor
The first 1:40 seconds taught me what my teachers would’ve taken a whole day to teach.
Being sick kinda shows you how little school teaches in reality
THANK YOU SO MUCH, very helpful since my exam is in 2 days !!
Maaaaaan ur saving my semester
thanks!! its helping in 2020

No cuz why are you better than all my teachers
Thankyou so much,I was struggling with this😭,But now I am clear,Thank you so much
Why is it that some random youtuber has provided more help to me then my own chemistry teacher?
You are better than Khan academy
what if ur not given the EN values how would u do it
have to memorize 😢
this is so goood. that's perfect explanation ,i wanted to prepare the lesson and this just summarized the 10 pages in my book!!!
Thanks so much, this was explained way better that any of the notes my Chen teacher had us copy from the board

Jon Marco Sanchez sadly there are exceptions such as H2O and NCl3
thank you man.. I was looking for this comment
Great video, thanks a lot!!!!!!!
This makes sense, however I still don't really understand what a dipole moment is or how to find the electronegativity values
Actually Christina...for the elements..they already have an original constant electro negativity value...so when it involves two elements together...and asked to get there net electro negativity charge...d subtract one with highest EN value from the smaller one bearing in mind the whether is gonna b higher than or equal to 0.5(i.e being polar ) or Less than 0.5(i.e being non-polar)..😊
Ah hope this helps😊
so in every bond(except for same atoms) we have a slightly positive and negative atoms?
What do you do when you don't have the electronegativity values available to you? I find it hard to assess polarity because of that.
Kelvin Fadojutimi Try using the trend on the periodic table. Electronegativity increases as you go across the period from left to right. It also increases as you go up a group from bottom to top. Keep in mind this excludes the noble gas and F is the most electronegative atom in the periodic table.

you are a god amongst men
God bless you. Honestly
thaanks so much it helps me a lot
thank you so muchhhhh
Sir i want know en defference in S and H is just 0.4only it is non polar covelent bond similar to C &H bond but why use delta symbol
5:07 what I learned was s has 2.6 electronegativity, and forms polar covalent bond with H (Dc=0.5). can someone explain
Great explanation
The Carbon Hydrogen is Nonpolar covelant Bond. Because non polar value is 0 - 0.4
in ethane I believe that it has polar bonds but non polar as whole
brilliant however you failed to indicate the type of bond at the border, example if the δEN is = to 0.5 like in the case of CI
therefor the non polar covalent bonds electronegativity have a δEN less than or equal to 0.5 not just less than 0.5
How to identify which is more polar HO-CH3 or CH3Si-CH3?
God bless you
Thank you
suddenly ap chem is easy
We need dipole moment examples where there’s actually dipole moment all these videos just contain examples without dipole moment
Are lone pairs considered in dipole moments?
Harshani Lakshmi if it has lone pair is polar
Would you ever considered making videos on biochemistry ?
how do we figure out the electronegativity values for the MCAT?
God Is Great, May God Bless him and you all and your families
What about bonds that contain more than 2 elements?
I think it’s a sum of the dipole moment vector arrows
How do I the polarity of bonds w o knowing the electronegative value? In my syllabus, we have to recognise the polarity w o using it hais
Just know the periodic trend for electronegativity. I forget on the spot, but I think that electronegativity increases as it goes from left to right on the periodic table, while it decreases as it goes down. Just compare locations of the elements and it should help out.
@@lovedog1012 the electronegativity increases from left to the right of the table. Owh I seee. Thanks weh!
@@lovedog1012 owh sorry didn't read through ur comment carefully just now haha yep u re right hehe
@@afanboy5370 Glad to help!! Just double check, though. I'm positive that it increases from left to right but not too sure.
@@lovedog1012 yes yes I did. And you got it right! May God bless you!
9:05 why
I suggest increasing the volume on these videos or projecting a bit more
At 1st u mentioned that if the EN is lesser than .5 then the bond is non polar... If thats the case, then hows O-F contains polar bond if the EN is 0.5? Plz sir, respond to my question asap🙏
Samina Yeasmeen you answered your own question. It’s not less than 0.5, so it is a polar covalent bond. 0.5 is not less than 0.5, it is 0.5 therefore polar.
it's 5 EQUAL TO or greater/less than
i am confused as to why the methane bond is considered non polar when the arrows all face the same direction making it polar T^T

Can someone help me....!! How it will be one polar and the other is non_polar I didn't understand this 😫😫😫😫😫😫
I love you
how do you know that carbon is partially positive and oxygen is partially negative?
oxygen has a higher EN so its negative
tamborts
i hate school
all this time i thought u were drawing the number 8 🤦♀️
polah

Is it working??
Jesus Christ Is Lord and Is The Only Way To Heaven🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽🙏🏽❤️❤️
Polar is greater than 0.3 while Nonpolar is 0.3 and below. Plz fix and reuplode with correct information
we got told its less than 5 non polar and greater than 15 polar?
Ec ❤️ty
But the electronegativity of O is not 3.5 it’s 3.44
