OmG!! I'm reviewing my chemistry from years ago and it's sad how much I forgot ... but I kept getting stuck on why the shape of water is wedged but not something like CO2. People kept saying the EN and atom size etc ... which sort of made sense but I knew I was missing something. Then boom!! Lone pairs taking up space!!! It's so friggin simple!! Thank you!
Great explanation, and supporting visuals! One question came to mind after showing the unbounded electrons, then the positive charge of the oxygen nucleus in the same area: why doesn't the unbounded electrons cancel this positive charge? Is it because the electrons are mobile, and will migrate away? What happens to the unbounded electrons orbital?
Watching again, I may have been confused by the colors, reversing their meaning. Red is more negative, and blue is less negative. Therefore, the unbounded electrons are in the negative area.
1:10 But if we follows the rule that opposite charge attracts, then won't the partially positive Hydrogens come closer to the lone pair instead of moving away?
If I am understanding this correctly, the hydrogen has already been stabilized by the bond from oxygen therefore it is not “positive” at that point. The predominant charges there would be the two pairs of negative electron which repel each other forcing the two hydrogen bonds apart.
But if positive and negative charges atract, why don't the positive hydrogens want to migrate towards the unbonded electron pairs that cause the tetrahedral structure of the molecule?
sir i have a quetion.(not related to this topic), in lewis dot structure of NO(nitrogen monoxide), can O donate its one electron to N (after forming double bond and N having 7 electrons in valance shell)in order to complete the valance electrons of N. I recently saw your octet rule exception video and this came in my mind. Please reply
NO is an interesting compound. Often it is described as having a three electron bond: en.wikipedia.org/wiki/Nitric_oxide#/media/File:Nitric_oxide.svg .
thankyou but if the two hydrogen atoms are on opposite sides doesnt that cancel out the effect of the negative charge and cause the molecule to be nonpolar
Since water has two lone pairs and two atoms it won't be 180 degrees. Something like CO2 has a different molecular geometry and is non-polar (see ruclips.net/video/SnBH-yy4Tkc/видео.html).
You still didnt answer the question as to why the water molecule is polarized due to the magnetic attraction and repulsion of the electron placement and the proton placement. When you showed the example of a nucleus with two e- bonds, the e- were 180 deg apart because the negative repulsion of the e- to the other e- is felt equally. So why does the P+ of the hydrogens bonding to the Oxygen not place the Hydrogens 180 deg away from each other if there are (2) e- pairs and (2) hydrogen bonds? 360deg divided by 2 equal forces of (+) and (-) of (2) electron pairs and (2) protons from the Hydrogens, each repelling force would be at its' maximum arc distance from its repellent charge. IE: The (2) electron bonds would be at N and S of the Oxygen and the (2) Hydrogen bonds would be at E and W of the Oxygen. Since the Oxygen has a stronger force to attract the e- to it, then the center would be more (-) and the outer would be more (+), but it the charges would still be in balance with no polarity of the water molecule. What is the reason for this unbalanced distribution of charge because these charges should be at 90 degs of each other and 180 degrees from their same charge, but they're not. The (+) charges are 104.45deg away from each other, not 180deg for a balancing of the magnetic forces.
This video allowed me to understand electronegativity and polarity mere hours before my chemistry exam. thank you.
how did it go?

this is the clearest explanation i watched
Amazing explanation with very helpful visuals! Thank you!
you're RIDICULOUS. that little 3d bit with the jiggle physics? AWESOME. keep it up!
Hey, thanks!
you made it crystal clear .......sir thank you
An awesome combination of visuals and explanations

Hello from Cambodia, well done explaining.❤️
Thank you! 😃
great explaining prof 🔥💚

Hey man, Great Video. Do you mind letting us in on this software showing the lewis structure please?
I get it now! Thanks a lot, your short and nice videos help a bunch
Glad to help!
Great explanation

Man you post the videos so late, I mean I finished my high school😭😂.
Congrats on graduating HS and all the best in college!
SIR do we have to predict whether it will be soluble or not when its like an element eg silicon with fluoride?because it is not in solubility table...
I would expect with something like that you would be provided the information. But my guess is that this would react with water.
Sir, I still have a question so when the water had a bond angle of 180° instead of 105° what is it?? Is it a polar or a nonpolar molecule?
Since water has two lone pairs and two atoms it won't be 180 degrees. Something like CO2 has a different molecular geometry and is non-polar (see ruclips.net/video/SnBH-yy4Tkc/видео.html).

Water molecules are made of 1 Hydrogen atom and 2 Oxygen atoms always have been and always will regards Graham Flowers
its H2O my guy lol
@@jairdavila6073 Yes H - 2 O not 2H - O or O - 2 H go back to school stop spreading misinformation and lies regards Graham Flowers
Can anyone just answer me starting with " because" why is water a polar??
CO(NH3)2 is a polar non polar or kovalen?
Do you mean urea, CO(NH2)2 ?
@@wbreslyn yes

Im beimg forced to watch this, im not really paying attention
Me too!
Lub uuuu😂😮
Yikes! Oxygen has 6 valence electrons, not 8! And hydrogen has 1 valence electron, not 2!
You explained it very well .
In which country do you live?
No just asking , like which country has this much high level of IQ .
👍👍
I’m pretty sure he is American. Though I may be wrong
I'm in the US but I don't think it has much to do with IQ!
You are correct!
