Intermolecular Forces 

I used to recall the term Hydrogen FONds to remember the elements involved better. The letters in caps represent the elements. :)

This is the best RU-vid channel for any kind of help in Chemistry! I just hope my AS goes just as good as you explained these bonding! Thank you so much.

This is better than reading the heavy coursebooks. My cambridge AS chemistry exam is in about 2 hours. Thank you for these videos 👏

I don't think you realise how much you have helped me with your chemistry videos. They are all very useful and you mention all the key points and your explanations are understandable. Thank you so much and I will definitely be watching your videos through out my chemistry A levels. Thanks again

You deserve to get famous. You are really good! Your lectures helped me alot thanks!😀

That's a class way to describe vander waals forces

Cheers for these, great to watch when i need to review stuff! :)

Thank you for the great videos which help me to revise for my AS exams, i have already spread the word about your brilliant youtube videos. P.S. in Topic 2 New AS Edexcel edition there is no video on solubility which is part of the specification, it would be great if you make one.

This is awesome 👏🙌. Understood every bit of it 🙊.thanks for these videos sir !

Omg that was so clear. Thank you so much!!!

Thanks for the Video, I have always found this topic a bit confusing. Thanks for clearing it up!!

We need more people like you. Thank you sir

Thanks big help, hate how many names London forces have, very annoying

For the year 2 section of chemistry, my sister was not able to find some of the chemistry topics. Would you please able to make some videos on the last few topics, please. Your a great lecturer, i appreciate what you have done so far, Well Done!

Thank you for these videos they really help

thank you so much Mr Chris Harris, this was very helpful

This is a great video! Just wondering, why do the London forces increase depending on Mr of the molecule? Is there a reason why it is not electron/proton number? I'm aware this is an old video but hope u see this! thanks

I finally get it, thank you so much

Thank you so much! this helps me a lot!!

Am I right in thinking that any molecule has London forces?

You're such a bloke. Thanks for the videos bru

Great video, thanks a lot!

Hi, thanks so much for this video. you save the chemical day! just had a small doubt. since the basis of a london force is in the temporariness of its dipole interaction, how can there be london forces in polar molecules? like for instance, in H2O. every bond is polar and has a permanent dipole, so how is it supposed to facilitate *temporary* dipole induction..? idk if that makes sense, but pls let me know. Thanks:)

hi, i love your videos. so clear and easy to understand! i read the PH3 has got permanent dipole dipole imf, can u pls explain why

How do you know which molecules have a permanent dipole?

When showing bonding between water molecules there needs to be 180° around the hydrogen involved in bonding. H2O------H--------OH. The molecules should also be bent/ non-linear.

Are Van Der Waals force and London Forces the same thing? Or is Van Der Waals = London Force + Induced dipole interaction

sir , what exactly is the difference between van der waal forces and dipole-dipole forces , because they look the same in a way. thanks

Hi +Allery Chemistry I'm slightly confused, the red box says 'The bigger the MR the bigger the the VDW force' Do you mean IMF instead of VDW force?

AMAZING video

How do we know CH4 has only van der Waals forces? like what are the indicators that differentiates the type of bonding with types of compounds?

How do you know they have a permanent dipole? Is it got to do with the electronegativities ??

This was so helpful!

"The bigger the Mr the bigger the VDW force" shouldn't it be "The greater the number of protons the greater the VDW force"? I really dont get how the Mr of molecules can affect VDW forces.. Only increasing the protons would increase the number of electrons Please correct me if i am wrong. Thanks for taking the effort to make these wonderful vids.

thank you very much!

Thank you 😊

Thank You so much!!!!!

I don't get how do you tell whether it has a delta+ or delta- charge

Does this mean that a compound or element that has hydrogen bonding automatically has the other two? Thank you for your videos I'm writing my AS this May, I'm so scared.

Wappuuuuuuu

Surely hydrogen bonds should be called hydrogen forces, as they are intermolecular forces?

Is it possible to draw two hydrogen bonding in two water molecules?? Reason please

Hi, do you have a video explaining hydrogen bonding and the elements between which it can occur?

is this enough detail?

11:44 CONSTANT VIGILANCE

london force can exist between h-cl and h-cl? or can it only be in diatomic molecules?

Is this the new OCR specification?
