The strongest reducing agent among the following is:

  • A
    $\mathrm{SbH}_3$
  • B
    $\mathrm{NH}_3$
  • Correct answer
    C
    $\mathrm{BiH}_3$
  • D
    $\mathrm{PH}_3$

Solution

The stability of hydrides decreases from $\mathrm{NH}_3$ to $\mathrm{BiH}_3$ but their reducing character increases down the group.

Hence, the correct answer is option: 'C'.
