In this video, you'll learn a super simple technique to determine if a molecule is polar or nonpolar. It is very easy. We first start by discussing what polar and nonpolar means. Then we go through the technique which involves a checklist of two criteria. Lastly we go through 6 examples that are all different to reinforce the technique. By the end, you'll know exactly to easily determine if a molecule is polar or nonpolar.

thank you thank you thank you. I have been crying about polarity but this has really helped and I actually understand it now. I wish more professors would teach like you.

[@cool_orbeez52]

Thank you so, so much! I did great on my test after watching this video and a few others on your channel. I’ve been struggling with this unit, and you really helped me pull through my test.

omg, finally after an hour trying to figure out how to determine polar or nonpolar, finally i got it!! big thanks~

Why is water polar if it's central atom oxygen has no lone pair of electrons. And all the atoms around it are same ?!!!

4am and I got a chem test tmr, I don’t understand the polar non polar stuff but this video is a life saver. I appreciate it

[@afrahchishty2936]

this is the most legendary chem video i have ever seen.

[@wolfierockz25]

This is really helpful. After the semester being moved online in March because to COVID, I felt like I didn't learn much from CHEM I. Now that I am in CHEM II I have felt confused, but this made much more sense to me!

[@nehemiahantoine8161]

You're in CHEM II? I am in Chem I and they are expecting me to learn this stuff. This video really does help a lot! I will take CHEM II next semester. I wonder how it's like.

[@p90p90]

I am sharing this with everyone in my class struggling with polar and non polar. Thank you good sir.

[@amitabhasisters6146]

I finally got a better understanding of this because of your amazing video! Thank you so much!!🙏🏻🙏🏻

[@chumchimlaem4343]

How to apply this for ch3ch2och2ch3? This is non polar but if we follow the rule above this is polar

[@tahmina.taghi95]

What a perfect explanation! Could you please clarify also this case for N2H4? Since here we have 2 same central atoms, and the molecule is symmetric, the dipole moments should cancel each other.

[@KavithaKavitha-qn5ec]

I don't think why so stupid videos get million views,likes, comment but the actual ones don't this video should desrve lot

[@StudyHoursV2]

4.5/5 Understanding , What I learned: very hard for molecule to be nonpolar, non polar if the molecular shape around central atom has no lone pairs or if it does its either square planer or linear, 2 all atoms around the central atom are the same.

[@Eyazcal]

I can not thank you enough! This video and your video on drawing Lewis Structures have made things so much easier to understand for me. You are great, and your videos have probably saved my grade in chemistry now!

[@irshadirshad6510]

Why is water than polar if it's central atom ( oxygen) has no lone pair of electrons. And all atoms around the central atom are same ??!!!!!

[@dharshinid391]

Thanks a lot . It helped me to strengthen chemical bonding in my neet preparation

[@ruleaus7664]

How does this work for PClF5?That's nonpolar, even though the atoms aren't all the same around the central atom.

[@adiel9918]

This video is so so helpful!! Thank you for simplifying this concept! I have a question. What about when you have c2h2f2? Because that can be drawn as a cis or trans. And we learned that the cis is polar but the trans is non polar. Do you mind explaining that example!

[@hetchaudhary5982]

Thanks sir really helpful 😊

hello.. what about TiO2, is that polar or non polar? thanks

[@yooonie9457]

works great the only molecule that I had trouble using this strategy was c2h2

What about H2O How its polar if it satisfy linear and all atoms around are the same

thanks alot....it was really helpful for my engineering entrance exam

sir is H2N2 polar or nonpolar? why does my prof say it cancels out and is nonpolar

hello sir. May I know if H2SO4 non polar or polar? From your lecture it should be non polar since there are 4 Os surrounding the central atom S, however 2 of the Os has 3 lone pairs. does that make H2SO4 polar?

[@anthonygregorio2208]

These are shortcuts do not always work. How about C6H14? Your rules do not apply to it.

[@tahminagafurova8733]

This molecule contains only carbon and hydrogen so it will be non polar. Molecules with only carbon and hydrogen will always be non polar.
