Homework 3.71

Postby Miya McLaughlin 2B » Mon Oct 17, 2016 7:21 pm

For this problem in the text book, it asks you to select the Lewis structure that is "likely to make the dominant contribution to a resonance hybrid."

What does it mean by "resonance hybrid" and how do you determine if it makes a contribution?

In class Professor Lavelle said that the lewis structure that has the most of the elements that have a formal charge of 0 will make the greater contribution because it is the most stable.
So it part a) Xe and F have a formal charge of 0 in the first one, while the second one has Xe with -1 and one F with 0 and the other one with +1
and you would compare the formal charges with part b as well.
The resonance hybrid is,what I like think of it, as the average of all possible correct lewis structures.

Hopefully that helps :)
