honestly, this is my first time writing a comment on UA-cam for someone, but I want to thank you. You have been helping me for 6 semesters! doing math, chem, and physics in a smooth easy way. I really like hearing your voice
Nicely done. I have one comment regarding the direction of the dipole moment: please keep in mind that electric dipole moments always point from negative to positive charges, i.e. in the opposite direction from that shown in the video. In fact you did use the correct definition at 2:15 where dipole moment \mu is defined as "charge times separation distance". If you use vectorial notation for dipole moment \mu and displacement r instead, this will naturally give you the correct result, i.e. dipole moments pointing toward the positive charges. Also, this is not an issue of chemists using a different definition for dipole moments than physicists. Although it seems that the majority of chemists is not aware of this misconception (see reference below). But who is to blame them? This has been passed on over generations and you will find dipole moments pointing the wrong direction even in standard chemistry textbooks and ... on the web of course. The arrow notation which you used, with the cross at one end and the arrow-head at the other was apparently introduced by Linus Pauling. It was originally intended to signify the direction of transfer of negative charge, i.e. the directions in which electrons are moved. Either he himself or others later then erroneously associated this cross-arrow notation with the dipole moment itself. If you are sceptical - as you should be - look up dipole moment in the online Gold Book of the IUPAC (International Union of Pure and Applied Chemistry), always a good place to resolve disputes on the definition of chemical terms. Hovick and Poler actually also wrote a nice article about this very issue in J. Chem. Educ. 82 (2005) p889, "Misconceptions in Sign Conventions: Flipping the Electric Dipole Moment". For some reason UA-cam didn't let me post a doi link to their article so you will have to look it up if you want to dig further. I hope this helps. Keep up the good work.
thank you so much. idk if im gonna pass chem but if i do its all thanks to u:') i rly like how ur videos dont trigger my anxiety, it lets me settle down and learn
At 7:18, i thought that this molecule would have a weaker dipole moment because dipole moment is the separation of positive and negative charges. For the nonpolar molecule, if the charges are facing the opposite direction, doesn't that mean a higher separation (a.k.a. greater dipole moment)?
Yeah very right Actually same thing happen to me I got answer of every question at the last Thank u so much u r very great tutor Many good words from my side ur lecture really helps in my exam May god shower his blessings on you 👌👌👏👍😊😊

I have a lot of questions, 1. lipid can also have Dipole Moment right? 2. From Q1, does that mean Lipid is momentarily dissolvable in water? 3. Water is polar molecule, why does it not induced non-polar lipid into polar polar lipid and make it dissolvable? I have done research online, for a couple of days, but as I get deeper, I couldn’t find a proper explanation. 4. Why Soap form a structure called Micelle? What happens if I don’t have oil in water, does Micelle structure still exist? 5. Micelle has a similar structure to phospholipid, how do soap get rid of phospholipid bilayer? but first, how do oleate past through the phospholipids layer, if the layer of phospholipids are densely connected, which means there would be no place for oleate is step in?
Yo. Very huge fan of ur vids. But there is one mistake. The Electronegativity difference of C and O is 1, which gives 19 - 37% of ionic character, but you got 10.4, which is not within the limit for the ionic character
molecular geometry of a molecule decides whether a molecule is a polar or not , which also determines dipole interactions exists or not , even though a molecule is polar or not . if the dipole moments cancel out , it is a non polar . if there is net dipole moment , it is a polar . for ex : CO2 is a polar molecule , but due its linear structure , the dipole moments cancel out , so therefore it is a non polar molecule . H20 is a polar molecule , also due to its bent shape struture , the dipole moments add up , so net dipole moment exists . So water is a polar molecule . Am i right ?

sorry for the dumb question..but can I say that the larger the dipole moment of a molecule, the easier it is to form non-covalent bond to other molecules (ionic bond, hydrogen bond, Van der Waals)? I am new to this concept so I'm just trying to understand the significance of dipole moment
Han Zou its polar because the bond between c and h is nonpolar but the bond between h and cl is polar. There is nothing that can cancel out the vector of cl so it overall c2h2cl2 is polar
Anyone know why the magnitude of charge of proton/ electron doesn't get doubled when putting it into the Mionic=QxR equation? Because i thought we were measuring the gap between their charges, I would have also thought the difference between them would be taken to get the magnitude of charge, as opposed to an average of the two. How I'm being stupid?
periodic table im using does not have same electronegative values as yours. my Hydrogen is 2.20 and Carbon is 2.55. So there is less diference of 0.5 in
you say in the first part that chlorine is much bigger than hydrogen but I thought the trend for atomic radius was that the atoms get bigger as you move to the left and down on the period table??
How do the arrows in CCl4 cancel? I mean I see that the ones going up and down cancel each other, but the ones on the left and right are pointing in completely diffenent places. How possibly do they cancel?
Because Carbon needs 1 electron and Oxygen provided that. You can imagine this as a CH3 + OH molecule if it makes it any easier. The topic is concerned about the separation of these charges when the molecule is formed.

Well it’s actually not quite right. Its not always polar if its bigger than 0.5. It depends on what periodic table your using. In my case for example it’s 0.4
According to the Linus Pauling scale of Electronegativity, the EN of Hydrogen is 2.1 and Linus Pauling Scale is the most widely accepted and used scale of EN.

Hey.. if the difference in electronegativity in the compound is 0.5 and that was nonpolar.. then why was the other compound also 0.5 and was polar?
Thank you a lot

Am i right ?
Very nice and informative video
You have a wonderful voice..
This is of such great help
increase electronegativity difference -> more polar
top right is most polar (F is most polar element)
Thank you so much. You are awesome.

Also i always enjoy your lessons..thank you
Sir, can you tell me which calculator you use
Now that's a Dipole Moment

THANK U SO MUCH I FINALLY UNDERSTAND
What about chcl3 and H2O which have highest dipole moment and why?like how do we know this one have highest dipole moment?
Here cuz my teacher didn’t teach us this but it’s on a test review sooo.
so for the quiz, if the instructor asks us that: Is C2H2Cl2 polar or non-polar, how can I answer it?
Han Zou its polar because the bond between c and h is nonpolar but the bond between h and cl is polar. There is nothing that can cancel out the vector of cl so it overall c2h2cl2 is polar
@@orehit3980 Hi, what about 5:56?
Thank you very much I love you to the moon and back
since we add 2 different charges (+)ve and (-)ve should it be (1.6+1.6) * 10^-19 Coulohms
Thank you sir.
A huge help for meee ❤️

how would you calculate the observed dipole in a scenario where it's not given? i mean, when it's not observed?
wait, what happened to the exponents that were not the same in the 2nd problem, 10^-29 and 10^-30
how would you calculate the actual molecular dipole moment between C and O if the observed is not given?
you say in the first part that chlorine is much bigger than hydrogen but I thought the trend for atomic radius was that the atoms get bigger as you move to the left and down on the period table??
He was referring to the bond dipole between C-Cl and C-H, not the atomic radius of Cl vs H.
bless you kind soul
how did u get the 1.78 D I DONT UNDERSTAND
U didn't show how u calculated it using the formula
2:16, Dipole moment= Charge * Distance of Seperation
THANK YOU VERY MUCH!
haha,u started with the question i was looking for
Hey bro ur videos r vvvvvvgood
But plsss try to increase the volume of speech
2021 anyone?
how do you know the electronegativity value ?
According to the pauling scale. You can check somewhere
love it
You rock!
Thanks a TON !!
How do the arrows in CCl4 cancel? I mean I see that the ones going up and down cancel each other, but the ones on the left and right are pointing in completely diffenent places. How possibly do they cancel?
the thing is that they are being equally atracted by the carbon, so none of them are more polar than the others
It's a 3d image
One cl at the top
One at the bottom
And other two at opposite sides (one at the back).
thanks very much
can you teel us the program that you use
where do the charges come from?
10:02 WHY DO WE CONSSIDER THE C-O to have +1 and -1 charge , please explain that . thank you

What would you say?
Is non polar always going be 0 for dipole moment
Thanks a lot my very grateful it's really helping me out.
Well it’s actually not quite right. Its not always polar if its bigger than 0.5. It depends on what periodic table your using. In my case for example it’s 0.4
The electronegativity of Hydrogen is 2.2
I think he's correct. It's 2.1 (from the periodic table)
According to the Linus Pauling scale of Electronegativity, the EN of Hydrogen is 2.1 and Linus Pauling Scale is the most widely accepted and used scale of EN.
I feel that I'm missing a notion..
Pls can someone explain y oxygen has 4 negative charge and hydrogen has 4 positive charge.
Thanks a lot👍
