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

Options

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

Answer

D

Explanation

Both `CO_2` and `N_3^(-)` are linear. Hence `N_2O` must be linear. Further two N atoms must be bonded together as that in `N^(3-)` Hence the actual structure from the knowledge of valencies would be `N-=N^(+)-O^(-)`
