Polarity of Bonds and Molecules

[7munch0]

Thanks for the video. You are a great teacher!

[nutmeglet]

thank you for this!

[amandipdhillonsingh]

I wish you were my teacher.

[780lelo]

that was very helpful thanks:)

[Sluo1947]

THANKYOU omg...

[Swiin3NeTwOrk]

Wordsss cannot express how much I learned in 4 mnutes than I did sitting in a college classroom spending thousands of bucks when I learned this for free. Thanksss!!!!

[Mcat941]

This video is completely wrong. Carbon with 4 hydrogens is NON POLAR! He meant to say that if all elements OTHER than the central atom are different, it's polar.

[missswatimahapatra]

First of all, C and H are NON POLAR.

not helpful.

[nabeek999]

@missswatimahapatra c and h are polar the difference is .4 which makes it a polar bond

[sofothemofo]

Thank you! Extremely helpful!

[MXMGamer]

CH4 is non polar!!!

[natiepooh2002]

I am studying for the CSET and this help me so much.. SNAP is definitely in my note cards.. .Thank you thank you thank you.

[gonsalves103]

I don't understand how C-H is polar. From what I've learned you're supposed to subtract the electronegativities of the 2 elements you're comparing (bigger one minus smaller) and if the difference is bigger than 0.5 it's polar, and 0-0.5 it's nonpolar. And C with 2.5 minus H with 2.1= 0.4... the part with SNAP helps though

[xoxrandomgirlxoxlol]

@gonsalves103 That's bonds. Doing that you're looking at which atom within the compound holds the electron closer to it. But when you consider lines of symmetry you're looking at polarity as a molecule rather than bond. If it weren't for that- every molecule that wasn't diatomic would be polar, but it's not like that. Just imagine those bonds being rubber bands. If you pull them equally from all sides they're evenly distributed and the polarity is canceled out.

[nickasu420]

idk what you are talking about but a C-H bond is still non polar. Their electronegativities are close enough to be considered non polar.

[xoxrandomgirlxoxlol]

@nickasu420 Even the slightest difference in charge can cause the slightest change in position :)

[ElysianRed]

thank u so much

[brainiac723]

I love how this guy is sick and teaches better than my own teacher. Makes me wonder what this guy could do if he wasnt sick.

[vkolomiyets]

Can you please come in and substitute my teacher for the rest of this year?? Thanks!

[Thehouseonmars]

My teacher doesn't even bother teaching really :O This was so incredibly helpful! THANK YOU, you wonderful human being!!!!

[Harleysville21]

this guy is 100000x better than my teacher

[0RPH3U5the666r3ml1n]

@Harleysville21 sad but true

[TheBosahE]

I just learnt more in 4:47 minutes than i have this whole semester.

[Swiin3NeTwOrk]

@TheBosahE Werddd! That snap thing helped alotttt

[aharmon83]

Thank you for this video!!!!

[iloveloveloveJB]

I just thanked God for you.

[saniyeleenatalie]

Very happy to find you on you tube. Thank you so much



[torque7793]

I love you.

[BamBam123456789ish]

technically the 'snap' acronym can be used for the bond also. If the bond is symmetrical, it means they are the same element and is therefore nonpolar...

[annadd10]

I too was getting stuck on what was the difference between the bond and the molecule... this one helped me the most out of all the polar bond postings I've flicked through! Thank you!!

[XhubiuXRock]

THIS is what we had to know. that bond is not molecule! thanks a lot

[latino919]

I LOVE YOU ! 

[simplenamehere]

YOU SIR, HAVE SAVED ME

[mgfire2008]

Bond polarity is determined by electronegativity between two atoms. C-H bonds are always NON-polar. Carbon's electronegativity is 2.5 and Hydrogen's electronegativity is 2.2. This difference is less than .5 meaning the bond in NON-polar. It is very hard to always generalize this way in chemistry there are always going to be exceptions to those rules like SNAP.

thnx doc
