Which of the following oxides of nitrogen is a linear and asymmertrical molecules?

Options

A. `N_(2)O`
B. `N_(2)O_(5)`
C. `NO_(2)`
D. `N_(2)O_(4)`

Answer

1

Explanation

`N_(2)O` molecule has a linear asymmetrical structure and is a resonance hybrid of the two forms:
`:overset(-)overset(..)(N)=overset(+)(N)=underset(..)overset(..)(O) harr :N equiv overset(+)(N) -underset(..)overset(..)(O):^(-)`
Other oxides have symmetrical structures:
