ALEKS: Predicting bond polarity

[@colinchatman7418]

you are seriously the only reason I'm going to pass chem THANK YOU

[@RoxiHulet]

Nah - you're the one doing all the hard work! I'm so happy that I'm helping, though!

[@samanthaschuessler8966]

Thank you so much for these videos!

[@RoxiHulet]

You are so welcome!

How do I know ones close to eachother are actually polar without a chart of their electronegativity values? I was never given anything like that

[@aidenmoro7583]

What if there is a double bond, like with the two lines? I got a problem like that on ALEKS. Does it not matter?

[@RoxiHulet]

Great question! It does not matter - you are only comparing the two atoms.

I try to avoid things that directly give me the answer, but watch your videos on a regular basis. In this case I got Cl and F. It says they are polar. lol They also gave me Br and Br, Cl and Cl. Those are obviously non-polar, but it outright says non-polar to Cl and F is wrong. :/ yeehaw. lol Edit, I just went with the electronegativity play on the periodic table and got it right. Just saying that that one in particular is considered polar, at least today.

[@rowansteins]

Electronegativity is provided on the Aleks periodic table. Next time please don't say an answer is correct and go back on it because it is confusing for those who watch for the answers only.

[@corinne5396]

The first answer is incorrect. The other option is correct and F is more electronegative.

finish the video before you comment

@@corinne5396 no, the point is to listen to the explanation so you can do it yourself. The video is 4 minutes long.

cl ---F. is wrong . should be polar
