In this video you will learn how to determine what intermolecular forces act between different molecules. We will introduce 1) Dispersion forces - forces all molecules possess due to temporary dipoles 2) Dipole forces - forces molecules posses if polar and 3) Hydrogen bonding - A sort of super dipole that results from hydrogen being bonded directly to N, O or F. We will then compare the strengths of these intermolecular forces and discuss how they relate to boiling point.
To understand how we know when a molecule is polar, please watch this video: • How to tell if a molec...

You just taught me my entire unit of chem in 10 minutes god bless you.

@macyzimmerman 3 года назад

i love that you went through problems! most people just explain the forces but don’t show us how to apply that to actual problems so this really helped! you teach better than my prof!

great video but that is not steam above the water. It is condensed water vapor.

If in the last exercise we had ionic compounds those would have the greatest BP, rigth?

@Badgerbahalwan 2 года назад

thank you for the great video. quick ? tho.. for the first problem in the practice problems, i came to the conclusion that there should be H-bonding. My reasoning is that since its intermolecular forces (between molecules) there would be another molecule with a partially negative N and it would want to bond with the H (partial positive) and that would then be a H-bond. is this correct?

@RealChemistryVideos 2 года назад

Hey Amir, You are 100% correct that the nitrogen will be a little negative and hydrogens ever so slightly positive. To have hydrogen bonds, you need to the larger partial charges that come when a hydrogen is covalently bonding to O, N or F. Then you get a relatively large partial negative/positive and the strongest IMF - hydrogen bonding. Basically, since H isn't bonded to N through a covalent bond, there is no hydrogen bonding in this molecular.

Please what software did you use in making this video?

@RealChemistryVideos 4 года назад

I make a presentation on powerpoint and use a template that has a blue square in the top right (where a video of me teaching is eventually placed). Then I use an ipad with Doceri to scroll through and annotate the slides. Doceri also lets you capture all of this annotations and audio. While I annotate my slides I am also recording a video on a camera and (when I am not lazy) a separate audio file from a nicer microphone. I put all of these video/audio sources together with sony movie maker. Happy to share more if you have more questions.

@aliciananatabi5003 4 года назад

If hydrogen bonding occurs in only F,O and N then what about C2H5OH(ethanol)

@RealChemistryVideos 3 года назад

Ethanol has hydrogen bonding since the OH at the end represents an H directly bonded to an O.

@meganebeaupre5140 4 года назад

What is ion-dipole force?

@RealChemistryVideos 4 года назад

Hi Megane, The ion-dipole force occurs in mixtures of ionic compounds and polar compounds. This force is stronger than any discussed in the video. Good question!

@ltshugoki583 3 года назад

For hydrogen bonding does a N,F, or C have to be bonded directly to the hydrogen atom

@RealChemistryVideos 3 года назад

Correct. So a molecule with a structure of O=C-H would not have hydrogen bonds, where C-O-H would.

@ltshugoki583 3 года назад

@@RealChemistryVideos ok thanks

@devnarula2003 4 года назад

isnt ion-ion stronger than hydrogen bonding 4:00

@mariagarcia-estreyer2493 4 года назад

I'm pretty sure

@jolk4459 4 года назад

Wdym? All of these are ion to ion bonds, intermolecular forces are just three categories created to group said forces by relative strength. I might just be misinterpreting what you’re trying to say though. Or I could be wrong. Probably the ladder lmao.

@RealChemistryVideos 4 года назад

by ion-ion forces, do you mean the forces present in an ionic bond between say a cation and anion? These are certainly stronger but are considered intrAmolecular forces. Because they are within a single ionic molecule. There is a force stronger than any of what we discussed here that occurs in mixtures, those forces are called ion-dipole forces. This occurs whenever there is a mixture of ionic compounds and a polar compound ( like salt water). I hope that helps!
