Which one of the following group-15 hydride is the strongest reducing agent?
- a
- b✓
- c
- d
Strategy: Relate reducing power to the stability of the hydride bond.
Step 1: Bond Length Trend Down Group 15, the size of the element increases, causing the bond length to increase and the bond strength to decrease significantly.
Step 2: Reducing Power As the bond dissociation enthalpy decreases, the ability to donate hydrogen increases. has the weakest bond and is thus the strongest reducing agent.
