Part B. 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.
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 of the different structures, which are called resonance forms. The cyanate ion ([OCN] − ) is capable of forming three different resonance forms.
