Everytime coming back home from school, I mostly have to youtube everything in order to understand (95% of the time, not kidding), and this man saves me everytime. I can't express enough gratitude to this man. Thank you so much!
At first, I'd look stuff up and be surprised when he covered it. Now I realize that I could look up how to send a rocket to the moon or how to bake a cake and I already know Organic Chemistry Tutor has me covered with a 3 hour long video covering the topic with examples.
Hello, I was a teacher myself, I am now 80 years old. I don't want to know what my students said about me back then. At the time, however, it was unfortunately not possible to interrupt me because the student just had to go to the toilet. You couldn't rewind me either because you hadn't understood something. So these are heavenly times for a student today, who can learn everything much more comfortably. If he wants to.

There's an ERROR: if you look up on google then AlN melting point is 2200 Celsius degrees while that of MgO is 2852 so the answer at 3:16 is incorrect! If you look at the molecules in terms of Electronegativity then it would make sense because EN of Al is 1.5 and N is 3 => AlN EN difference is 1.5 while EN of Mg is 1.2 and O is 3.5 => MgO EN difference is 2.3, greater than that of AlN which means MgO has greater ion-ion interaction, resulting in its higher melting point. The video is amazing as always! Thanks a lot!
Your videos are great thank you so much. You are literally the reason I’m passing because no one understands my professor’s heavy accent so we are basically teaching ourselves
if you can concentrate well enough are are running out of time, speed it up x1.5 ( i have a test in 30 mins and im watching this in my schools bathroom lmao)
24:21 that subtraction by multiples of 8 thing is freaking awesome! Why didn't my professors teach me that when we were learning lewis structures?!! Actually kinda pissed now... that would have saved me SO MUCH time on the 'molecule structure' type questions earlier in the semester!
He teaches tricks we were never taught of....obviously this guy is that much more experienced in this field of teaching.thank you.A level chemistry is crystal clear once I see your videos
I can never thank you enough for what you do for me. Things that would normally take me weeks to understand take me days, all thanks to you. Thank you so much organic chemistry tutor. You're a hero to so many of us.
Man I love you so much thank you for always saving me! I don’t understand anything from my teachers so I always rely on RUclips videos and especially yours! Ty
I'm an auditory learner, so my textbook doesn't help me much. This video cleared up so much confusion for me! P.S. thanks to your channel, I got a 5 on the thermochemistry test without reading the textbook!
organic chemistry tutor you are a lifesaver and I am so subscribing because it is the least I can do when you have literally saved me from utter failure and everlasting confusion
Modular classes are hard because its basically self study at home, but I am so thankful for your videos. They really help a lot 😃 I just wanna say THANK YOUU 🙏
i have chem homework due tomarow. Was putting it off because i thought i understood it. Opened the page, saw the first question, immediately looked this up.
I think the first example of dipole dipole interaction that you gave happens to be carbon dioxide however its structure is a bit out of place, in carbon dioxide, carbon is double bonded to two oxygen atoms each with a lone pair. It has ldf forces in it and is a non polar molecule.
I got to understand everything in one night. You are so brilliant! Thank you so muchhh! I wish you were my teacher in chemistry and physics then maybe I'd have better grades 😭❣️
uhm idk if this could help or if this is right but according to the reviewer i have with me, the higher the intra molecular force, the higher the melting point.. for ion ion interaction, the force that hold the unit togethr is electrostatic. MgO stays solid at high temperatures. solids have high intermolecular force thus having higher melting point.
Thank you for these videos, truly! Although my syllabus does not distinguish between ion-ion interactions and ion-dipole interactions, it's nice to know more.
3:20 AlN has a lower melting point than MgO because AlN has more covalent characteristics than MgO. Al3+ is very small thus it has a high polarising power and N3- IS very large thus it has high tendency to be polarised (in other words N3- has a high polarisability. The higher the polarising power of the cation and polarisability of the anions the more covalent characteristics the compound possesses.And we know that compounds with a covalent nature have relatively lower melting point than compounds which are more ionic in nature.
@@nahfid2003 Mostly. Aluminum falls on the periodic table at the point where metals stop and nonmetals start, and since it's a gradual thing and not an absolute thing, those elements are called metalloids. Aluminum does exhibit more characteristics of a metal than say Germanium, which is why I asked the question. Chemists tend to group it with metals but not all chemists so IDK.
In the sulphur dioxide section, the lewis structure is wrong and the charges are also wrong since the charge of both sulphur and oxygen is negative. Correct me if I'm wrong.
The intermolecular forces between CO2 molecules are dispersion forces, while the forces between CO molecules are mostly dipole-dipole attraction forces. So, why does CO2 have a higher boiling point than that of CO?
Just want to reiterate how thankful I am for this video; before watching, I simply had no idea how the bloody hell to determine if molecules are polar or not, but this video makes life so much easier by actually elaborating on the nuances that professors unfortunately forget to explain. Thank you!!
Thank you so much for this video. My exam is in a few days and I was having difficulty catching up with this section. Please keep making these educational videos!
how different are ion ion interactions from ionic bonds.I read somewhere that ionic bonds are intramolecular so I would appreciate it if you could clarify
I don't know if I had commented on this video before, but if I did, well I'm commenting again, thank you so much, you really really did help me understand intermolecular forces and I really appreciate it.
One question. Based on the Lewis structure of CO. The carbon atom should bear a formal negative charge, while the oxygen atom should bear a positive charge. How come is charge distribution swithced in the section of dipole-dipole interaction (11:08)?
