Question #152e2

Answer 1

This one's tricky in that `N_2O` demonstrates resonance and two contributing Lewis Structures can be drawn. That is:

`[:N -= N^(+) - O:::^(-)]` `harr` `[::N^(-) = N^+ = O::]`

To support the structure containing the triple bond; an `sp - sp - sp^3` hybridization is used. To support the structure with the two double bonds; an `sp^2` - `sp^2` - `sp^2` hybridization is used.

Explanation:

The graphic needed to illustrate the hybridization certainly exceeds my artistic skill set, but was unable to find a suitable graphic online.
So, with undeterred determination, here's my best effort.
