Question

Bond dissociation enthalpy of $E?? (E =$ element$)$ bonds is given below. Which of the compounds will act as strongest reducing agent ?

• A. $NH_3$
• B. $PH_3$
• C. $AsH_3$
• D. $SbH_3$

Answer 1

Answer: (D)

$SbH_3$

Answer 2

$SbH_3$ will act as strongest reducing agent as it has lowest bond dissociation energy and $Sb??$ bond is weaker.
