The correct order for bond angles is :

Options

A. `NO_(2)^(+) lt NO_(2)^(-) lt NO_(2)`
B. `NO_(2)^(-) lt NO_(2)^(+) lt NO_(2)`
C. `NO_(2)^(-) ltNO_(2) lt NO_(2)^(+)`
D. `NO_(2)^(+) lt NO_(2) lt NO_(2)^(-)`

Answer

3

Explanation

`|{:("Species","Steric Number","Geometry","Bond Angle"),(NO_(2)^(+),2+0,"Linear",180^(@)),(NO_(2)^(-),2+1,"Trigonal planar","less than "120^(@)),(NO_(2),2+1" odd electron","Trigonal planar",134^(@)):}|`
therefor eth eorect order is `(3)`. Because th ethird bonding site (in `NO_(2)`) is ocupied byya single electron rather than by a lone pair it is reasonable for the bonding angles to be opened up
