Reducing nature [other reduces and self-oxidises] Size propto Reducing nature.

Q. Arrange the hydrides of group $15$ in the correct order of reducing nature

$N H_{3} < P H_{3} < A s H_{3} < S b H_{3} < B i H_{3}$

$N H_{3} > P H_{3} > A s H_{3} > S b H_{3} > B i H_{3}$

$P H_{3} < A s H_{3} < S b H_{3} < B i H_{3} < N H_{3}$

$P H_{3} > A s H_{3} > S b H_{3} > B i H_{3} > N H_{3}$

Reducing nature [other reduces and self-oxidises] Size $\propto$ Reducing nature.
