Which of the following has the highest proton affinity ?A. Stibin `(SbH_(3))`B. Arsinie `(AsH_(3))`C. Phosphie `(PH_(3))`D. `Ammonia (NH_(3))`

Answer» Correct Answer - D
High electron density on small `N` atom repel lone pair, making it more available for protonation. From `P` to `Bi` size of atom increases and so lone pair becomes less available for protonation.
