Which of the following has maximum bond angle in the anionic part in the solid state ?

Options

A. `XeF_(6)`
B. ICN
C. `N_(2)O_(3)`
D. `N_(2)O_(4)`

Answer

B

Explanation

Anionic part of ICN solid state has maximum bond angle `(180^(@))`.
ICN(s) exists as `[I_(2)(CN)^(+)][I(CN)_(2)]^(-)` having linear structure of anion `N-=C-I^(Theta)-C-=N` having linear strucute of anion `N-=C-I^(Theta)-C-=N`
