WebAmong the hydrides of Group-15 elements, which have the (a) lowest boiling point? (b) maximum basic character? (c) highest bond angle? (d) maximum reducing character? Solution (a) P H3 : Phosphine has a lower boiling point than ammonia because of the presence of hydrogen bonding in the latter. Web17 mrt. 2024 · > Among group 15 hydrides, ammonia has maximum basic character. This is because a small sized nitrogen atom has the highest electron density. With increase in the atomic size on moving down the group, the electron density decreases. So nitrogen can easily donate a pair of electrons and act as a base. Hence, the option (B) is the correct …
