Chapter 4 #13 Part D

Write the Lewis structure, VSEPR formula, molecular shape, and bond angles for each of the following species:
(d) N2O

The most stable Lewis structure should a triple bond between N and N -- why does the answer key show a not-as-stable Lewis structure?

One of the two possible answers does have a triple bond between both nitrogen atoms. I think the other one is included because if the formal charges are calculated, both structures have an atom with a +1 charge and an atom with a -1 charge, making them similar in lowest energy.
