![]() PBr5 Lewis structure and its molecular geometry.Because repulsion is minimum in electron pairs at this position. So, there are 4 regions of electron density(3 bond pair + 1 lone pair) around the central atom.Īccording to the VSEPR theory, the central atom with four regions of electron density adopts a tetrahedral electron geometry. The electron geometry of PF 3 is Tetrahedral, because, the phosphorous central atom has one lone pair and it is attached to three bonded pairs as well. ![]() The electron geometry consider bond pair as well lone pair while determining the geometry of any molecule. Now, What is the electron geometry of PF 3? So, while determining the molecular geometry of PF 3, we will consider the repelling effect of the lone pair present on the phosphorous central atom, but the lone pair will be invisible when we look at the actual molecular geometry of PF 3. It should be noted that, Molecular geometry only consider bonded atom while determining the shape of molecule, it doesn’t count lone pair, but the influence of lone pair(repelling effect) will be counted on overall shape of molecule. ![]()
