Question

Compare bond angle of Nitrogen family hydrides down the group.

Answer 1

Down the group the bond angle decreases as :
the force of repulsion between the bonded pair of electrons in NH3 is more than in PH3

Answer 2

$\huge\textbf{Answer}$


» Down the group atomic size increases, electron negativity decreases, tendency to attract electron decreases, repulsion between bond pairs decreases. That's why bond angle decreases down the group.
