Asked By: Natosha Changoluisa | Last Updated: 3rd April, 2020, Phosphorus is in group 5 of the periodic table, meaning that it has 5 valance electrons. As a single phosphorus trifluoride (PF3) molecule has three bonds (between phosphorus and fluorine) and one lone pair of electrons, the steric number is four. Moreover, this further can be confirmed through the hybridization which says a single PF3 molecule shows 75% characteristics of p orbital. One sp3 hybrid orbital accommodates the lone pair of the electrons of the phosphorus. As the lone pair repulsion is stronger than the bond pair or bond pair-lone pair repulsion, it reduces the bond angle. STUDY. C. On the… 4.
