Draw as many resonance structures as you can for (a) the form of fluorescein present at
Chapter 15, Problem 15.56(choose chapter or problem)
Draw as many resonance structures as you can for (a) the form of fluorescein present at pH 5 9 (p. 730), and (b) the fluorescent group of the green fluorescent protein (p. 730). Use the curved-arrow notation to derive your structures. Be sure in both cases that an unshared electron pair on the anionic oxygen is involved in the resonance interaction.
