# Do ambident nucleophiles form functional isomers?

I came across cyanide and isocyanide in an example for functional isomerism. As they are also ambident nuclephiles, I wanted to know if other ambident nucleophiles would also exhibit functional isomerism.

Thanks

1. Cyanide ($$\ce{CN}$$) and isocyanide ($$\ce{NC}$$)
2. Nitrite ($$\ce{ONO}$$) and Nitro ($$\ce{NO2}$$)
• Nitpick: Cyanide is already mentioned in OP's question. Here is a different example: "thiocyanate $\ce{-SCN}$". – Nilay Ghosh Jun 21 at 8:45
