MCQ
Among $NH_3 , PH_3 , AsH_3$ and $SbH_3$ which one is a stronger reducing agent?
  • A
    $NH_3$
  • B
    $PH_3$
  • C
    $AsH_3$
  • ✓
    $SbH_3$
✓

Answer

Correct option: D.
$SbH_3$
d
$SbH _3$ is the strongest reducing agent because $Sb ^{5+}$ is most stable in its respective group so it gets easily oxidised so its the strongest reducing agent.
