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),289,322,279,255):}`

A

`NH_(3)`

B

`PH_(3)`

C

`AsH_(3)`

D

`SbH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Weaker the E-H bond, stronger the reducing agent i.e., `SbH_(3)`.
