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 KZitem TV with the Organic Chemistry Tutor.

@Jessica Whittingham wait so by adding up the vectors, you mean just subtracting the electronegativity of each atom and seeing whether or not it equals 0? 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 :) )

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.

Just know the periodic trend for electronegativity. I forget on the spot, but I think that electronegativity increases as it goes from left to right on the periodic table, while it decreases as it goes down. Just compare locations of the elements and it should help out.
