AQA A-Level Chemistry - Intermolecular Forces

This video covers the sub-topic of Intermolecular Forces from the main topic of Bonding.
Beginning with the forces and then details about each, it ends up looking at some past exam questions.

The students you teach are so bloody lucky to have you as a teacher

Hey, I am a human from the future. That is not how it actually works. You see, different situations, environments, and some other stuff contribute to what will ensure the most efficient teaching and learning. In a classroom environment, this teacher could have difficulty sharing the exact same information within the same time frame, with the same voice tone, and with no package loss. haha. Due to it being a video there are no other students to provide distractions and thus increase the duration of the lesson and package LOSS!!!!! dun dun dun. Indeed my friend, sitting alone watching a video and taking notes is not comparable to being in a class with other people. In the same way, you can not compare flashcards with just reading the notes. Both work well, but to what extent, and for who? WHO WHOO .... this reminds me did you know, owls hunt other owls? Maybe we should alert the parliament of owls. haha, owl puns are fun. Do you know what else is fun? Finding out whether we live in a simulation and to find out why our miserable souls have been placed on to the earth, why we are not who we think we are, Why we exist!!!!! AND Why I will never be able to finish all of the game theory and vsauce videos in time for tonight's anime marathon.

[@amirkashani11]

I wish my Chemistry teacher was half as good as you, everyone in my class uses your videos for revision/learning. Thank you for all the effort you put into them

[@sophizoey]

You are currently saving me from being failing AS Chemistry all together. I come home after a lesson and just switch your videos on straight away because my teacher teaches me nothing (He thinks he is a million times better at teaching than he actually is). I am constantly getting told I shouldn't be doing Chemistry, but thanks to you I am actually understanding all the content, because I am actually learning and being taught it. I sit on a evening playing you videos with my textbook open as if it was a lesson. (Because I am clearing gathering nothing from my actual lessons.)

[@MrERintoul]

+Sophie .Jayne That all sounds like a right hassle. But I'm glad you're coping and finding ways to deal with things. Let me know if there's anything I can help with and keep working hard!

Seriously thank you so much for these videos, I have been basically teaching myself Chem and I have learned more from your videos in one day then the entire month and a half I have been in school! Thank you!

Your videos are absolutely amazing! I'm understanding chemistry so much more with your explanations.... thank you so much! Also, I was wondering what you mean by the titles of these videos "NEW & OLD SPEC", are you referring to the new 2016 SPEC or does "NEW" mean the 2015 spec? I'm asking because I've realised this video was uploaded on Feb 2015.

Umer Khan Spot on - glad it was of some help!

[@borojenxx4193]

Thank you! This was really tough to read about as it requires lots of thought. I tried the exam questions at the end before you give the answers and I got them all right apart from the last one. I mentioned that "Hydrogen bonding only takes place between molecules with partially negative Oxygen, Nitrogen and Fluorine atoms attracted to molecules with partially positive hydrogen atoms" I didn't mention the phosphorus's negativity :s

[@MrERintoul]

Boro Jen xX Good work!

[@antony_7970]

Just a quick observation. In question 1c) I’m pretty sure the strongest intermolecular force would be van fer waals. This is because the molecule will adopt a tetrahedral shape in which the dipoles will cancel out and it won’t be a polar molecule.

[@regaali8766]

only started my as levels and your videos are great for me, I have fun and learn whilst watching them, only wish that there were these videos for biology aha, thanks very much.

[@CuboPhile]

You are an amazing teacher!!! I wish you were my chemistry teacher at school!! I understood everything except for the phosphine one. Why can't H-bonding take place with Cl? Chlorine is more electronegative, right? I would be grateful if u could clarify it in the comments

[@ethanchal]

Thank you! Very helpful :)

[@MrERintoul]

***** No problem! :)

[@shraddhasheth2023]

Hi, can you do exam questions at the end of every video please as they are really helpful and can you make a video on electronegativity and which parts of the spec it links to?

[@chowderz6903]

Thanks, You're videos are amazing but i was just wondering about a few things. at 26:30 do HI, HBr and HCl have dipole-dipole bonding? Also at 31:36 would you talk about bonding (i.e. covalent bonding) because the question says in terms of bonding or can this also mean hydrogen bonding?

[@zahrahalibhai71]

really helped thankyou

[@izzcaine3398]

You're an amazing teacher !! really appreciate it

[@MrERintoul]

+Ilhan Ali Haha I'm not sure you'd agree if I was in the class with you! But thank you for the kind words!

[@Ruhit_99]

Did you make a video on electronegativity?? Since you knew straight away the differences between electronegativity when predicting the hydrogen bonds.. Also for the last question could you have wrote there isn't lone pairs in phosphine or is that wrong? Many thanks.

Sir, when we are finding out the electronegative difference for dipole-dipole ......what is the range for the big difference in electronegativity??? 35:54

[@abdulgilani5881]

for question 1e) at 32:30, can you mention F2 is monoatomic and therefore will have weak van de walls due to its small molecular size

[@twennywan3265]

Haha, it's funny how my AS Chem qualified (somehow) teacher learns from your videos too. He doesn't even know why cinemas have staggered seating. He's probably reading this whilst he's teaching...his mouth how to consume crisps. Nice to see you continuing your videos, keep up the good work.

i was having a hard time learning this as I'm currently a GCSE student studying a levels independently and your videos are bangin'! thanks for making this channel!

[@noshiamir8390]

keep it up 👍

[@MusicCrazyLover23]

one question- why does the electronegativity change in iodine molecule ..resulting in induced dipole? what causes this difference in one side of the bond being more positive and the other more negative??

[@Joee-jt7zp]

thank u my g

[@Gemxni_]

Can you please do a video going over the Electrochemical cells topic from the A2 spec please?

[@alaynahurooj1995]

Thank you so much wow

[@MrOreoMuncher]

Are dipole-dipole considered Van Der Waals too? The revision assistance guide (wjec) is treating both dipole-dipole and induced dipole as van Der Waals forces.

[@DanGBP1]

quick question. why can’t it be hydrogen bonding with something other than N,O,F that is electronegative

[@dno.16]

for question 1c) ccl2f2 wouldnt it be symmetrical so therefore nonpolar?

[@blobar1231]

32:30, bonding? What you stated was an intermolecular force, is that right or I'm missing something here?

[@MrERintoul]

+Vanessa Costello Yep. What I've written is 100% correct. The reason is due to the bonding being simple molecular. In this bonding the weak VdW forces play a key role.

[@FXRain]

Just to make sure, do the examiners allow the use of the three dots for a shorter way to say therefore? By the way these videos are really helping me out thanks a lot for your effort.

[@MrERintoul]

+FXRain Yeah for real! I love me some 3 dots.

[@celinebasma6264]

34:26 can you say that iodine has a bigger atomic radius than fluorine and therefore has more electrons and so requires more energy to break vdW’s forces ? Rather than saying that iodine is bigger ? Does it mean the same thing and will it get you the marks ?

[@adamburgess7890]

Defintion of electronegative? It might've been in the video but I've watched it in parts thanks.

[@redtext3359]

Hello, May I know why the hell does CCl2F2 have dipole-dipole forces? Thanks! :D

[@samlaight9705]

For question 1 (c) - I thought the dipoles would cancel because the shape is tetrahedral (four delta negative halides are surrounding the carbon atom? And therefore van der Waals are the only intermolecular forces present? I could be completely wrong though.

[@tylerwareham940]

Thank you for this video I feel I understand however there are definitely gaps in my knowledge.. 1) how do you know if a molecule is electronegative and which one is more than another? and 2) how do you know how many lone pairs a molecule contains?
