Chemistry | Intermolecular forces | Physical properties of organic compound
Intermolecular forces and how the affect the physical properties of compounds (Boiling point, Viscosity, Vapour pressure and Volatility).... This video explains it all in a simplified way.
Enjoy!!!

You must realize that this videos or lessons you put on this platform are timeless. This is still going to be relevant for quite some time and, even the future generation will make use of them . Chief , keep doing what you do best 🙏
Mlungisi Nkosi is literally saving my future at this point 😭👍🏼because I need to get good marks for my varsity acceptance, especially for physics. Thank you for being able to explain work in a manner we can all understand!. I've been watching you since Grade 10 and my understanding of physics has improved. Thank you ❤️

Hi ❤️ I'm currently doing my matric year and I got a 78% for my Physics March test. Mlungisi Nkosi really did a number for me during my time of studying for the paper
this is the best video ever on intermolecular forces, from this video i got an A on my test and even impressed my teacher with my answers. couldnt have done it without this vid thank you!

hi sir, i was wondering why it is that alkynes or alkenes will have a lower bp compared to alkanes ? is it because of the number of imf forces between them or something else

Sir i was told that phase is never considered because it involves the intramolecular bonds
Quick question,do they penalize us if we write CH3 instead of breaking it down???also when writing a structural formula,is there a specific side we should start on,like for instance maybe adding our alkynes and stuff??? because according to me its the same answer,but I need to know if there is a preferred starting point or either way is fine as long as the numbering is correct... I need to know this before I write tomorrow so please do respond. Thank you

Sorry sir , can you please consider that part whereby we are talking about Degree of branching (shape) , So I wanted to ask if I'm correct if I write it this way 👇 Compound A *Large surface area *Strong intermolecular forces *More energy required to overcome the intermolecular forces Compound B *Small surface area *Weak intermolecular forces *Less energy required to overcome the intermolecular forces
Good day sir, provided we have a secondary/tertiary alcohol and a carboxylic acid, will the carboxylic have a high boiling point or they'll differ due to an increase in Oxygen(O) in the alcohol compounds
@MlungisiNkosi
2 жыл бұрын
Yes carboxylic acid should still have higher BP due to the two sites of Hydrogen bonding.
@tsireletsolentsa7883

Please tell me what I'm missing because the only reason I think that causes all of that is test anxiety maybe . Please help while it's still early .
