Dion Advincula water polar because one side is more negative than another, the hydrogens want to give their electrons to oxygen due to its higher electronegativity. when something is polar it has a side that’s more negative than the others and because oxygen is more negative then the hydrogens it forms a point of negativity.

Sending energy to the spirit bomb of life to this brotha. I keep putting all my classmates on this channel and it's freaking amazing how much this man's content helps us. Helped me in math, computer science, and chemistry so far. Subscriber for life. Keep up the good work :D
I searched through tons of videos to find something explaining if how a molecule was polar or non polar, this video was the last one I needed because it helped so much, due to the fact that it was quick and showed easy ways to find its polarity. THANK YOU & keep up the good work
B doesnt have 8 electrons around it its an exception(it only needs 6 electrons) , i think the rest of the elements needs 8 electrons. therefor it DOESNT have the lone pair to form a trigonal pyramidal,it will form a trigonal planer . N needs 8 so therefore i will have a lone pair of electrons which WILL form a trigonal pyramidal
hanna issa BF3 is a trigonal planar (2Dim.) molecule with no unbonded pairs of electrons. In NH3 the N atom has sp3 hybridization, making it a 3Dim. tetrahedron. Tetrahedral atoms have, potentially, up to four bonding locations. In NH3, three of those locations on the nitrogen are occupied by hydrogen atoms. The fourth location is occupied by a pair of unbonded electrons. The unbonded pair tends to push the other bonded pairs away. The unbonded pair has a very strong negative aspect, whereas the negative aspect of the other three bonded pairs are "diluted" by the more positive hydrogen atoms to which they are connected. Therefore, the end of the NH3 molecule with the unbonded pair will be more negative than the opposite end. This makes the molecule polar.
@@simmy4619 if i'm not mistaken, polar and non-polar are just for covalent, so ionic bond is neither of them.. ionic is charged while polar and non-polar are partially charged ( that's why it is delta + or delta - ).. correct me if i'm wrong
@@heyheyheyhey376 ahh that makes sense. I think you’re right. So if the EN difference is equal to or greater than 1.7, it’s not sharing electrons, rather using the give and take method
Polar and non polar bonds do not equate to polar and non polar molecules. Polar bonds can be a polar or a non polar molecules, whereas non polar bonds is only non polar molecules.
@@heyheyheyhey376 But how can I calculate for Ethanol? I know Ethanol is non-polar.....but how should I calculate this like other covalent bonds by electronegativity?
chloe i’m going to need to choose between chem and physics by the end of this year and i still don’t know what to choose honestly. everybody’s telling me that physics are way too hard and that i won’t find work. i actually love them both but i prefer physics but i feel like i’m obliged to choose chem somehow:(
I didn't understand what my teacher is discussing about polar and nonpolar until I found this video and now I was able to understand polar and nonpolar. Thanks to this man, a lot.
yeah? really? what does it actually mean polar vs non-polar. why do we even care? why did chemists ever care to distinguish molecules based on this criteria? does not explain this at all. probably helped you pass some exam and just forget about it all. mechanical teaching and learning at its best!
Hi there! I know you probably get a lot of comments and messages but I just wanted you to know that you're great at explaining ideas and topics!!! Super helpful! I just want to thank you for putting videos like this out there because sometimes it is just so hard trying to understand and keeping up with the professors at the universities! I appreciate your time and effort!!! Thank you! Thank you!!
I just came from a recent video and all I could say is "he grew" OUR GUY GREW!! (motherly-tears) His voice, his speaking, his explanation, overall HIM 😭 god bless!
This helped me so much. I havent taken the first installment of chemistry in years and am currently in the second installment, having forgotten most of what I learned years ago. Thank you so much!!
If your main atom (like C in CH4) has got disconnected electron pairs your molecule is Polar because the distribution of electron charge on its molecule is not the same And if the atoms around your main atom are different then your molecule is also polar Just in case if you need it guys! Don't forget to draw the Lewis Structure 😉
I am taking physiology class right now as part of my prerequisite for my major, since chemistry is not a part of my prereq I never took it. I'm struggling in my physiology class because most of the contents in the lecture are on the atomic level, so some things my professor talks about just goes over my head. but this video has been really helpful for me!!! thank you!
Thanku .... It was really helpful ... earlier I was unable to distinguish between these two bt now it proved really beneficial for me ... Again thanku so much
could you make a video explaining what polar and non-polar exactly means I know in your video you explain how to identify it but it would be nice if you explained what all of it means thanks
i hope all the good things come into your life. you're saving so many lives just by teaching us one of the hardest subjects we could ever encounter. super thanks! i'm currently reviewing for a college entrance exam. whether i pass or not, i owe part of my life to you. always have a great day!
When you say that the molecule is symmetrical it is non-polar, how so? Because something like CF4 would have a tetrahedral shape which contains 2 bonds in the same plane, 1 going out of the page and 1 going into the page so it wouldn't be symmetrical. Please can you clarify what you mean by symmetrical? Thanks
tetrahedral is a symmetrical shape as if you cut a tetrahedron from any point passing through its axis you will get a congruent part of it , now talking about polarity : the vector sum of three bonds is equal and opposite to the 4th bond thus it is non -polar
Literally, have an organic chem exam tomorrow and I literally forgot that you could do this to figure out if a compound is polar or non-polar... THANK YOU SO MUCH OMG
Anything above or to the right of an atom on the periodic table has higher electronegativity. e.g. Li has higher electronegativity (1.0) than Cs (0.8), because it's 4 periods higher. C has higher electronegativity (2.6) than Li (1.0) because it's to the right of Li. Also, you can check this on most periodic tables.
@@nicolasa4life BH3 boron is in group 3 so there are no lone pairs and it's symmetrical. but PCl3 has lone pairs since phosphorus is in group 5 and that makes 3 bond pairs and one lone pairs of electrons. So it is not symmetrical.

No Problem
The Organic Chemistry Tutor why is BF3 non-polar and NF3 is polar?

N needs 8 so therefore i will have a lone pair of electrons which WILL form a trigonal pyramidal

How to calculate the electronegativity because its usually not mentioned in the question.
Anything above or to the right of an atom on the periodic table has higher electronegativity.
e.g. Li has higher electronegativity (1.0) than Cs (0.8), because it's 4 periods higher.
C has higher electronegativity (2.6) than Li (1.0) because it's to the right of Li.
Also, you can check this on most periodic tables.
+Preston Garvey I see.. tysm
How do you get these specific numbers, though? the (1.0), (0.8), (2.6), etc...
You'll have to look at a periodic table for that. But you can make general estimates for some of them.
use a data book of values
