Hello, I just subscribed for studying chemistry.
Thank you for seeing my question.
I saw the answer for this problem, but I could't
understand why the electron dots aren't drawn for the two
oxygen.
I think the right oxygen has 2 lone pair because of
the octec rule. Actually, I'm confused because the partial negative
charge of the right oxygen in the resonance hybrid comes from minor
contributor that has the oxygen having 3 lone pair. What is
correct?
