# Lewis structure of a compound [closed]

What is the correct lewis structure of ammonium cyanate ion? I do have a structure but it seems partially correct. If I'm wrong, then please inform that also.

• $\ce{NH3 }$ has a lone pair, $\ce{NH4^+ }$ doesn't. – MaxW Feb 8 at 16:31
• What lone pair? NH4+ has none. – Ivan Neretin Feb 8 at 17:57

First thing is that there will be no lone pair in nitrogen as the lone pair is donated to the 4th H+ ion. This forms the ammonium ion.

Now, cyanate ion is formed by [OCN]-. The negative charge is due to the three lone pairs in O (instead of two).
