Resonance Structure meaning

Postby madawy » Sun Oct 27, 2019 10:55 pm

I remember Lavelle telling us that the amount of resonance structures correlates to come feature of the atom, but I forgot to write it down? Does anyone remember?

i think it has something to do with formal charge

When we went over resonance in lecture, Dr. Lavelle defined the term as the state when some Lewis structure have multiple bonds in different equivalent locations. The greater the amount of resonance structures, the more stable the Lewis structure is.

I think the exactly quote you're looking for is that "resonance exists when you can draw multiple structures for a molecule with multiple bonds, wherein the arrangement of atoms are the same but the arrangements of electrons between the atoms are different." :) I hope this helped!

Resonance is a blending of structures with the same atom arrangement but different electron arrangements.

I have always been confused by this as well. I know that there are often multiple ways to show an atom's structure, and that the best one has a formal charge of 0, but WHY? How do you know how many resonance structures to draw? Any and all insight is welcome.

So is the resonance structure the average of all the possible lewis structures for a certain bond?
