WebMar 25, 2024 · $\begingroup$ It's worth noting that there is generally an "equivalence" between SMILES and resonance forms in most chemical drawing software, including … WebWhile both resonance structures are chemically identical, the negative charge is on a different oxygen in each. This is important because neither resonance structure actually exists, instead there is a hybrid. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. 2 comments ( 26 votes) Upvote
