Draw a Lewis structure for HNC and assign the non-zero formal charges to each atom. Draw the Lewis structures with the formal charges minimized.

Question

Draw all bonds and add all lone pair electrons. Also, add all non-zero formal charges to the appropriate atom(s).

Answer 1

H can only for 1 bond

C needs 4 bonds to have no formal charge

N needs 3 bonds and 1 lone pair for no formal charge

so it will be

H - C = N:
