The incorrect statement regarding 15th group hyrides `(EH_(3)).[E=N,P,As,Sb,Bi]`

Options

A. `NH_(3) gt PH_(3) gt AsH_(3)gtSbH_(3) gt BiH_(3)`:Thermal stability
B. `N-H gt P-H gt As-H gt Sb-H gt Bi-H,E-H` bond dissociation enthalpy
C. `NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3) gt BiH_(3):` Reducing character
D. `NH_(3) gt PH_(3) gt AsH_(3) gt SbH_(3) gt BiH_(3)`: Basicity

Answer

C

Explanation

Reducing character`prop(1)/(E-H'" bond dissociation enthalpy")`
Hence, correct reducing character is `NH_(3) lt PH_(3) lt AsH_(3) lt SbH_(3) lt BiH_(3)`.
