Which bond angle is high from PH_(3) and PH_(4)^(+)? Why ?

Answer»

Solution :In `PH_(4)^(+)` , bond angle is high because it is TETRAHEDRAL and angle is `109.5^(@)` .
In `PH_(3) , SP^(3)` hybridization occurs but non- bonding `e^(-)` pair present on P, So due to REPULSION and bond angle is decrease `(93.6^(@))`
