Polar covalent bonds & partial charges

Postby Annah Khan 1B » Sun Jul 09, 2017 9:55 pm

Hi, I'm having trouble understanding the concept of polar (and nonpolar) covalent bonds, as well as partial charges. Can someone please explain this further to me? And how do they relate to each other? Thank you in advance!

it is really helpful to know how to draw the structure of the atom first. The covalent bond is the bond that holds them together. Nonpolar covalent bonds have equal electro negativity therefore on is NOT pulling more than the other due to the atoms evenly sharing (e.g. Florine --Florine). Polar bonds happen when there is uneven sharing between atoms therefore one pulls more that the other always depending on its electronegativity (e.g. Oxygen--Florine *florine is smaller than oxygen and because of this it has a larger electronegativity value causing its polarity to point towards the direction of florine). electrons do play a part in the polarity but it would be hard to explain over a message because it's better visually. Anyways, hope this helped!
