Which of the following statemnet is wrong ?

Options

A. The stablility of hydrides increase from `NH_(3)` to `BiH_(3)` in group 15 of the periodic table.
B. Nitrogen cannot form `dpi-ppi` bond.
C. Single N-N bond is weaker than the single P-P bond.
D. `N_(2)O_(4)` has resonance structure.

Answer

`(1,4)`

Explanation

The stability of hyrides decreases from `NH_(3)` to `BiH_(3)` which can be observed from their bond dissociation enthalpy. The correct order is `NH_(3) lt PH_(3) lt Ash_(3) lt SbH_(3) lt BiH_(3)`

`{:("Property",NH_3,PH_3,AsH_3,SbH_3,BiH_3),(Delta_(diss)H^(o-)(E-H)//kJ mol^(-1),389,322,297,255,-

Alternate solution : `N_2O_4` may has four resonating structure but in NCERT only two resonating structure.Resonating structures of `N_2O_4` are
