Answer:
Isocyanates
Explanation:
The functional group is cyanate ion of the formula NCO⁻. The atoms in this functional group occur in a straight line giving it a linear structure. It has a singe C-O bond and a triple N ≡ C bond. It forms cyanate salts when it reacts with pure elements like sodium and other reactive metals as it has some acidic properties. It also forms complexes like silver cyanato [Ag(NCO)₂]⁻
