Cno- Lewis Structure. The central atom for cno should be c, since it has the lowest ionization energy. Carbon is the least electronegative, put that at the center, and then we'll put the nitrogen and the oxygen on either side.
The cyanate ion is an ambidentate ligand, forming complexes with a metal ion in which either the nitrogen or oxygen. It is an ambident nucleophile in nucleophilic substitution. Distance=1.276 ang___ between n1 and c3:
