Write three Lewis structures for the cyanate ion,NCO^-,where the arrangement of atoms is N-C-O.In the most plausible structure,

Question

Quizplus · Accepted Answer

The most plausible structure for the cyanate ion has a triple bond between N and C. This is because nitrogen has five valence electrons and needs three more electrons to complete its octet, while carbon has four valence electrons and needs four electrons to complete its octet. A triple bond between N and C satisfies both of these requirements. The formal charge on N in this structure would be F1F1F1S1F1F1F101, but this is not one of the choices given.
