Bond dissociation enthalpy of E-H (E = element) bonds is given below. Which of the compounds will act as strongest reducing agent? {:("Compound",NH_(3),PH_(3),AsH_(3),SbH_(3)),(Delta_(diss)(E-H)//kJ mol^(-1),389,322,297,255):}

Answer»

`NH_(3)`
`PH_(3)`
`AsH_(3)`
`SbH_(3)`

Solution :Weaker the E-H BOND, STRONGER the REDUCING agent, i.e., `SbH_(3)`.
