As a result, the PH3 molecule attains the shape of a trigonal pyramid wherein the three bond pairs form the shape like the base of a pyramid, while the lone pair remains at the top, maintaining a larger distance from all the three bond pairs. Total valence electrons pairs around By looking at the PH3 Lewis structure, we see, that there is only 1 lone pair present(2 dot electrons on the central Phosphorous (P) atom). The bond angle in PH3 is lower than the ideal value because of the large repulsive force exerted by the lone pair on 3 bonding orbitals. As the phosphorous atom belongs to the 5A group in the periodic table and hydrogen is situated in the 1A group, hence, the valence electron for the phosphorous is 5, and for the hydrogen atom, it is only 1. These lone pair on the central Phosphorous atom is responsible for the PH3 molecular geometry distortion. The followings are the conditions. After linking the three hydrogens and one lone pair of electrons in the tetrahedral form, it maintains the tetrahedral-like structure. As a result, it has a permanent dipole moment in its molecular structure. This force is lower between a lone pair and a bond pair, whereas it is the lowest between two bond pairs of electrons. According to this concept electron pair will prefer to maintain a considerable distance between each other, as this is said to reduce the repulsion in between the valence electrons. A Phosphine molecule comprises one Phosphorus atom and three Hydrogen atoms.
