Moreover, this further can be confirmed through the hybridization which says a single PF3 molecule shows 75% characteristics of p orbital. Hence, the fluorine atom goes outside in the lewis diagram whereas the phosphorus atom fetched the seat of the central position. My book says that from drawing the Lewis structure for the molecule below, you can conclude that it has dipole moment. Faraday Discuss. Firstly boron trihalides are trigonal planar and have an empty-and-small p orbital (violates the octet rule), so it is favourable that the p orbitals of the boron and the halogen atom will overlap; meanwhile phosphorus trihalides are trigonal pyramidal which is less favourable for orbital overlap, and the phosphorus . It means the molecule will produce four new hybrid orbitals of equal energy which corresponds to sp3 hybridization. As you see in the above structure, each fluorine has 6 electrons represented as dots and 2 electrons in form of a single bond, hence, the fluorine atom has a total of 8 electrons and it completed its octet comfortably.
