Unlock 5.0 school opening guidelines extended till Nov 30. We can … But PH3 has three bond pairs and one lone pair around P. Due to greater lone pair-bond pair repulsion than bond pair-bond pair repulsion, the tetrahedral angle decreases from 109° 28' to 93.6°. In essence, ph 3 is a Drago molecule and if we look at its bond angle data it shows that the p-orbitals have an angle of 90°.
