Determining the type of intermolecular forces present in different types of molecules; using intermolecular forces to rank molecules by their boiling points

[@stellar6519]

this explained the entire thing like nobody else could- thank you so much

[@MagilexYT]

I just wanted to thank you for making this so much easier for me to understand. Words cannot describe how thankful I am especially when I am studying for a unit exam for this specific topic. You are a fantastic teacher that I wish I had for this year.

[@RoxiHulet]

Oh thank you :) you made my day. Good luck on your exam!

@@MagilexYT Yeaaahhhhhhhh!!!!!!!! 🥳

[@markobaban2261]

Best explanation by far. Other videos of other creators weren't bad on this topic, but this gave more of a newbie approach that I needed.

[@jian1076]

Thank you!!! Neatly explained!

[@ruqiazainab1169]

I am impressed with the way of your teaching.... Thanks

[@nekofan4798]

Excellent explanation with examples !!! thank you so much now I get much clearer the topic!!! thank you!!

[@redcomet1717]

THANK YOU THANK YOU THANK YOU!!!!! this has really helped me for my test because my teacher only spent about 5 minutes on this topic!!!!

[@feelthe8d398]

I dont have words to describe u Thanks Kindly do some examples for every bonding for how their attraction increase

[@tracyjanepel6408]

Thank you so much for this. It was very helpful!😊

[@RoxiHulet]

Glad it was helpful!

[@heathermurray479]

Thank you so much!!! I understand this topic now! :)

[@lauraine662]

Thank you so much! I did not understand it when my teacher was teaching.

Thank you you helped so much for my final terms in college

Thank you so much

Thanks! One of the first few videos where I understood this lesson.

Is it possible to determine if a molecule is polar or non-polar just based off of the distance between the elements on the periodic table?

[@studytoss2631]

Same doubt

[@RoxiHulet]

Not with complete certainty. The only way that you can tell for sure is to calculate the difference in electronegativity between the atoms, and also to evaluate the symmetry of the molecule based on its geometry. If you are working on an assignment where electronegativity values have been provided to you, that's a good hint that you need to actually do the calculation. However, most assignments that I've encountered just simply ask you to make predictions based on the relative location of the atoms in the bonds. If two atoms are very far apart, you can feel confident that the bond between them will either be polar or ionic.

for I3-, why does the center iodine have 10 electrons? does it not follow the octet rule?

[@callmequeenc3582]

Thank you so much!! 😩😙

You are a truly amazing teacher. Thanks a lot

can you tell me the order of intermolecular forces in h20 , h2 , co2

[@anvaykelkar]

h2o, co2, h2 from strongest to weakest

[@gaurishagrawal9404]

For HBrO..isnt Br the least electroneg. and therefore should be the central atom?

[@RoxiHulet]

That’s not a foolproof rule, don’t rely on it too much. Halogens and hydrogens are almost always outer atoms based on their desire to form only one bond. That typically overrides the “least EN goes in the middle” guideline.

[@gaurishagrawal9404]

Your voice is so lovely

[@lonevoyager6026]

Aren't intermolecular forces between molecules and intramolecular forces are within a single molecule? HBr is only one molecule so why are there intermolecular forces present?

[@RoxiHulet]

Molecules, plural. It’s referring to the IMFs between molecules of HBr.
