Draw the resonance forms. (Hint: there are a total of three good resonance forms, including the first one provided above.) Please answer and explain why! I will rate.
a. Option a: First resonance form provided
b. Option b: Formal charge on the nitrogen
c. Option c: Double bond between nitrogen and carbon
d. Option d: Double bond between carbon and one of the oxygen atoms

Explanation: The first resonance form provided shows a double bond between the carbon and one oxygen atom, but there are additional resonance forms that can be drawn to show the delocaliation of electrons throughout the entire molecule. Option b would have a positive formal charge on the nitrogen, option c would show a double bond between the nitrogen and carbon, and option d would show a double bond between the carbon and one of the oxygen atoms. These additional resonance forms help to explain why the molecule is stable, as the electrons are delocalied and spread out over the entire molecule.
