Why is the single curved arrow shown insufficient to draw a resonance structure?
◦ The resulting structure would have an atom with less than an octet.
◦ The resulting structure would have a negative on the least electronegative atom.
◦ The resulting structure would have a negative on the most electronegative atom.
◦ The resulting structure would have a positive on the most electronegative atom.
◦ The resulting structure would have an octet rule violation.
