Man you are a solid speaker. I can appreciate when someone talks on a topic being certain of what they are going to say before they say it, while not pausing or using "like". How I've not found these videos earlier is beyond me.
hi, i'm a school teacher here in the Philippines. I really appreciate your videos cause they help me a lot in facilitating my teaching the students here. Keep it coming. God bless
hermest99: On average there would be as many repulsions as attractions. However, attractions move the charges closer thus increasing the attraction whereas repulsions move the charges away diminishing the repulsion. This results in a net attraction. Further this can result in a resonance effect between the molecules that stabilizes the attraction. Google "the strengths of van der waals dispersion forces" to find an excellent explanation of this.
I want to point this out, don't expect this set of videos to teach you things from ground zero , i mean, this playlist assumes some basic previous knowledge on chemistry. Then you will be able to absorb the information accurately
Can you please explain why they are a intermolecular? A molecule is 2 or more atoms joined together by let's say a covalent bond. The London dispersion force acts upon 2 atoms. Shouldn t that make it intramolecular? As a whole does it form a giant molecular structure, or what is holding the london dispersion force formed molecules together, and create a liquid like in the case of liquid argon?
Hello I just have a question. You said that w/ increased amount of pi-bonds there's an increased attraction due to london dispersion forces. I'm confused b/c thinking about saturated fats vs. unsaturated fats (contains pi-bonds), the saturated fats have a larger london dispersion forces b/c they have more surface or as you called it "contact area." So if you can clear that up, I'd appreciate it. Thanks in advance. Bozeman Science
Just one question Paul. The dispersion force causes an attraction via the induction of the temporary dipole, why is it called a dispersion force? It seems to be doing the opposite; could you clarify this? Thanks.
Darn, this couldn't have come out yesterday. My chemistry teacher set a challenge to do with LDF. But its alright this will help reinforce those ideas. Thanks for the video. Also i was wondering, do the instantaneous dipole moments of electrons have anything to do with their quantum spin?
Your soothing voice creates a sense of false confidence in my ability to succeed in chemistry.
lol
I will not write LOL
This video was 2yrs ago. I'm curious how many of the 370 who liked your comment passed :)
Creative
5 years later I do not remember any of this hahaha
Saving my medical school career one video at a time.
Nathie1230 de
hows the medical school going?
I hope you got into medical school!!!
saving my undergrad pre med career
are you a doctor now?? im so invested lol i remember seeing this comment when i posted mine 5 years ago
Your wish is my command. This is video 16 in a 71-part series on the new AP Chemistry course. I hope to finish sometime this fall.
Holy crap, you did it, thank you for your service to all science students, aspiring scientists, and ultimately, your service to the world.
Man you are a solid speaker. I can appreciate when someone talks on a topic being certain of what they are going to say before they say it, while not pausing or using "like". How I've not found these videos earlier is beyond me.
7 years later and still saving the day 👏
Very helpful! And way easier to understand than a textbook!
Explained it better than my chem teacher 😔 thank u for ur service
In which School you are ?

You seem so friendly and I can thank you enough for how much you've helped me in chemistry :)
Soooo helpful. Your videos have been my grade savers since sophomore year of high school... Thanks so much :3

r u still a teacher
You really cleared up how non-polar substances are dissolved. Thank you.

ty for this video , really organized and helpful in learning the concept.
Great, I have been reading about the London length of the protons in neutron stars and the electron seas that surround them. Thanks for loading this.
Congrats on 90k subscribers and thanks as always.
hey its been 10 years how is life
Your short 5 minute video helped more than 70 minutes of class in chem
this is so helpful all videos use very weird words but this video actually breaks everything down
but the forces of friendship are stronger than any other!
your profile pic is haunting
Not at all
Thank You, Professor Andersen! Your videos are so helpful and detailed.
Thankyou! Being able to see the atoms in motion really helps.
Very good, the pentanes example is excellent. Looking at previous comments, it seems that mentioning the correlation of electron motion will help.
Very clearly explained, easy to understand even with 2x speed. Great job
i need time to process this :D i had to go back like 10 times. but still, it's good! thanks!
hey hows life 10 years later. man its been a long time
You are a good teacher well👍👍👍👍. Your animation classes are helping to understand the concepts very well.Thank you so much
Originally, I am confused about London dispersion force. After your video, i totally understand how it works! Thanks a lot Mr. Andersen!:)
Watched your videos in high school and now I'm back watching them in Uni cos I forgot a lot of things LOL
What a fabulous video. This is one of the best.
I really like the way things are explained in such a simple and clear manner:)
This is the best video I found for this topic!

I have a test tomorrow, and you just made everything better
Great explanation sir
You're a life-saver, explained it so well. Thank you!
Nice! "
I was trying to learn these forces from 1 month but u made it easy". "Thanks"
So thankful to you sir. My teacher is awful and you just explained that with so much ease.
Thank you dude!! You explained really nice! Now I able to understand the whole concept.
he went through it fast, but helpful over all

This was fantastic . I liked the video and understood it very well
Great Job man!This is exactly what i wanted.Thanks a bunch.
I miss that sound track on biology vids. And as always you are utterly and amazingly awesome
That was amazing! The visual really helped!
Brilliant teaching style
Thanks for the great video! It was very clear and understanding, and I appreciate your videos.
Your voice is amazing 😭
Beautifully explained. Thank you

You have saved my life in 2017
Now it’s almost 2021!
VERY WELL explained! Cheers!
I finally feel I understand the London dispersion forces. Thank you!
Wish every school and collage have professor like him.
Yes, I learned what london forces are. Thank you for the video
Easier than text book
Thank u soo much
great illustrations
I'm not sure if that would translate to the TH-cam medium. You must have been a former student?
Great video for anyone studying cell biology / DNA / Proteins to watch
Very helpful sir. Keep it up👍
I liked your way of teaching
Great explanation
Wow hats of to you....nice explanation friend.........
Bravo! I feel like cheering :)
Excellent I appreciate yourteaching really really👌👌
Thank you so much! you explained this topic in a very interesting way
Thank you for a such elegant and clear explanation. Is there a mathematical equivalent to to dipole moment for London forces?
Thank you it helped me a lot. You had explained it in a nice manner.
You explained it so good. Thank you so much
Thank you! Great explanation.

nice explanation man.
Extremely helpful! Thanks!
Excellent teaching
Thanks a lot! it's very helpful and interesting. i really love your video.
man I always watch your videos.. keep up the great work, I will be back!:)
btw. is london dispersion force the same as dispersion force?
Yes, these are actually dispersion forces named after their founder Fritz London
Thank you
Wonderful video :D Thanks!
Helpful video bro....thanx
SO HELPFUL, THANK YOU!
THANK YOU FOR THIS I LOVE YOU
This is amazing! Thank you very much sir!
great explanation, thank you

Excellent video.. well said...great animation. .
Just one small doubt why does London forces increase with Pi bond....
Daipayan hati electrons are loosely held in pi bonds.Hence greater polarisability.
Thank you! My chemistry project is saved.
thanks
Thank You Helped so much studying for finals
certainly it is helpful. Thank you
Was very much helpfull... thanks!
it's awesome man..I just got full in chemistry.. tq a lot 😊😊😊😊😊
Mr Anderson, how is the matrix?
Thank you, this was really helpful :)
thank you very much !!!
Really Good Work :D
This video is so good
Thanks. Very helpful.
Thank you!
excellent video
Very helpful thanks a lot
it was very helpful...thnx
so good thank you very much
Very helpful thank you
Is the London Dispersion Force same as the van der Waals force?
HELPFUL Thank you!
Darn, this couldn't have come out yesterday. My chemistry teacher set a challenge to do with LDF. But its alright this will help reinforce those ideas. Thanks for the video.
