What is the Lewis structure of OCN-?

Answer 1

#O=C=N^(-) harr ^(-)O-C-=N#?

Valence electrons #=# #6_O+4_C+5_N+1# #=# #16#. Thus there are 8 electron pairs to distribute over 3 centres. Two resonance structures are avalaible as shown; since oxygen is more electronegative than nitrogen the one on the right might be a better representation of molecular structure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
