    Professor Organic Chemistry Tutor, thank you for an excellent analysis of Bond Polarity, Electronegativity and Dipole Moment in AP/General Chemistry. Once again, the practice problems are the best way to learn this material from start to finish. Problem solving improves students/non-students understanding of the material. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.

Otherwise, thanks so much i was rlly struggling in class today lol. The only part that gets me is the word choice for "canceling" or "not canceling" arrows. I get which way they face though thanks to you lol. Thanks a bunch! :} (btw it would be appreciated if you used an example as well :) )

    • @ChemSimplified
      @ChemSimplified 4 роки тому +8

      Kelvin Fadojutimi Try using the trend on the periodic table. Electronegativity increases as you go across the period from left to right. It also increases as you go up a group from bottom to top. Keep in mind this excludes the noble gas and F is the most electronegative atom in the periodic table.

      ​@@suryajandhyala You need the electronegativity values to figure that out. There's no way you can figure out if the molecule is polar or not without the values.
