Resonance structure

Postby Madeline Lequang 1G » Thu Nov 29, 2018 9:33 am

When making a VSEPR, is really that important that we get the corrext resonance? I know that it shows it as the most stable structure, but aren't double and triple bonds just treated as one region of electron denisty?

Yes so for VSEPR, I do not believe resonance structures matter very much as you're only looking at regions of electron density instead of types of bonds (as you said, double or triple bonds don't affect if a molecule is linear or trigonal planar, they are unrelated.) Regardless, I think that resonance structures are important to note even if you don't draw them all out so that you can better understand the hybridization happening in the molecule and correctly identify bond type (sigma, pi, etc.)
