which one stronger reducing agent BH3 OR SbH3?PELEASE ANSWER IN NO TIME

Solution

Reducing agent is that which reduces the other species and itself gets oxidized. Therefore best reducing agent will be that which can easily give electrons.
Now, SbH₃ acts as a strong reducing agent because of its large size as compared to boron so extraction of electrons will be easy from it because it has low ionization energy.
