For many compounds, it is possible to draw multiple Lewis dot structures that are simplifications of the structure of the true molecule. The actual structure of the molecule, called a resonance hybrid, is a combination of all the different structures, which are called resonance forms. The cyanate ion ([OCN]^-) is capale of forming three different resonance forms.
Draw Lewis dot structures for the three possible resonance forms for the cyanate ion ([OCN]^-), and assign formal charges to the oxygen and nitrogen atoms in each structure.
Draw all possible Lewis dot structures for the cyanate ion (OCN^-) by placing the atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Use square brackets to denote the overall charge.
