Which of the following is the structure of `N_2O` which is isoelectronic with `CO_2` and `N_3^(-)`?

Options

A. `N-N-O`
B.
C.
D. `N-O-N`

Answer

A

Explanation

According to isoelectronic principle, isoelectronic species usually have the same geometry. Thus, like `CO_2` and `N_3^(-)`, `N_2O` is also linear. It is actually a resonance hybrid
