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!
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?
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.
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.
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.
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!
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!
You just taught me my entire unit of chem in 10 minutes god bless you.
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!
A real help for my online classes. Thanks so much! I will recommend you to my friends.
omg I watched khan academy and many more. This video was by far the most helpful! thank you
I literally have my end of topic test tomorrow and you resolved all my doubts. THANK YOU
This made so much sense to me! Thank you for this helpful video.
THANK YOU SO MUCH! THIS HELPED ME A LOT! THANK YOU!!
Thank you SO much. You explained this so perfectly and I loved how you used examples which made me understand more. Life saver!
this video is lifesaver thanks sir thank you so so much
This is so helpful!! Going through questions really made me understand
Thank you so much!!!
THANK YOU VERY MUH IM WRITING TOMORROW AND YOU HAVE MADE ME UNDERSTAND MY WORK BETTER.
I now know how to determine inter-molecular forces. Great video, very cool!
This is the best video ever! Im gona teach this method to my students! Thankyou so much.
This helped me to know the differences in all 3! Thank you! 😊
Glad it was helpful!
Thanks brother
U taught me what my tutor couldn't
Really really thanks
Thank you for making this very helpful video! It really helped me studying for my chem exam :)
This helped a lot in preparation for my midterm quiz! Thank you very much and keep up the great work sir😁
awesome video. i understand sm better now for midterms!
Very good video, you explained it way better than my teacher!
Thank you very much for this very informative video. Well appreciated.
amazing!!!!!!! thank you so much..best video on this
video was awesome, understand it much more now ty
Thank you so much for these!! I am a student at GGC and these videos helped me SO MUCH!
I'm so glad!
This helped a lot :D thanks so much
YES finally I understand this stuff, thanks!
Great stuff! Thank you very much!
Awesome video. You do sound like Seth Rogen though. (That is a compliment)
Thanks! This helped so much

very helpful .
thanks a ton!!
The chemistry goat
thanks man you are the goat
thank you this helped me a lot! :)
Great Video!!
Great video!
BRO THANK YOU SO MUCH
If in the last exercise we had ionic compounds those would have the greatest BP, rigth?
Thank you for your help!!
Thank you so much !!!
Thank you so much
Thanks❤❤❤❤❤
u the goat man
great video but that is not steam above the water. It is condensed water vapor.
Please what software did you use in making this video?

isnt ion-ion stronger than hydrogen bonding 4:00
I'm pretty sure

SO GOOD!
For hydrogen bonding does a N,F, or C have to be bonded directly to the hydrogen atom
Correct. So a molecule with a structure of O=C-H would not have hydrogen bonds, where C-O-H would.
@@RealChemistryVideos ok thanks
What is ion-dipole force?
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!
You're what's been missing in my life
If hydrogen bonding occurs in only F,O and N then what about C2H5OH(ethanol)
Ethanol has hydrogen bonding since the OH at the end represents an H directly bonded to an O.
really help me a loooooot!
Thank you!
anybody else think he kind of sounds like Seth Rogen? haha love it though
Eister ong zhi xin
Thank you so much!
Great video!
thank u so much!
Thank you!!
