The P-Block Elements
Question
Bond angle in PH4+ is higher than that in PH3. Why?
Solution
Both are sp3 hybridised. In PH4, all the four orbitals are bonded whereas in PH3 there is a lone pair of electrons in P, which is responsible for lone pair-bond pair repulsion in PH3 reducing the bond angle to less than 109°28'.
