Question

Bond angle in ph4+ is higher than that in ph3.Why?2

Answer 1

Explanation:

In both PH3 and PH4+, P is sp3 hybridised. ... In PH4+, the HPH bond angle is tetrahedral angle of 109.5° . But in PH3, the lone pair-bond pair repulsion is higher than bond pair-bond pair repulsion. Thus, the bond angle becomes less than 109.5°
