The strongest reducing agent among the following is:
- a
- b
- c✓
- d
Strategy: Reducing power of group 15 hydrides depends on the bond dissociation enthalpy.
Step 1: Thermal Stability As we move down the group from to , the size of the central atom increases, leading to an increase in bond length and a decrease in bond dissociation enthalpy.
Step 2: Reducing Power Lower bond dissociation enthalpy means the hydride can release hydrogen more easily. Thus, is the least stable and the strongest reducing agent in the group.
