Sapling Resonance Structures

Postby Brianna Chen 3F » Sun Nov 15, 2020 7:35 pm

When I was doing Sapling, I noticed that they included the "non-favorable" structure in the answer when they were explaining the resonance hybrid. I thought we first look for the most favorable structure and then if there is resonance, that is part of the resonance hybrid?

The "non-favorable" structures and favorable structures are both included in making the resonance hybrid since the hybrid is a representation of all structures in one with variable bond changes represented by dotted lines.

The favorable one will be the one lowest in energy and contributes the most to the resonance structure, but the other less-favorable arrangements do contribute as well (just not as much)!

Another thing to note is that if a resonance structure is very unfavorable, it will contribute very little to the overall resonance hybrid, but it still contributes a very small amount because it is a possible resonance structure. The most favorable and lowest energy resonance structures contribute the most to the resonance hybrid since they are the most favorable, but all possible resonance structures have some contribution, even if very small.

Hi, I saw a video that describes picking the favorable resonance structure: https://www.google.com/url?sa=t&rct=j&q ... DlWdsxYqws

This helped me out for homework and textbook problems.
