Bond angle in PH4+ is higher that in PH(...

Bond angle in PH4+ is higher that in `PH_(3)`. Why?

Text Solution

Verified by Experts

In both `PH_(4)^(+) and PH_(3)` , atom phosphorus is in `sp^(3)`. hybridised state. `PH_(4)^(+)` is tetrahedral in shape and bond angle is `109^(@) 28^(1)` In `PH_(3)` due to the presence of one lone pair of electrons bond angle deceases from tetrahedral angle.
