Nitrogen do not form Pentahalides because of the non-availability of d-orbitals..where as Phosphorus have vacant d-orbitals to form Pentahalides.Posted by Shyam Prasad (student) on 2/10/09.n the case of Bismuth, due to inert pair effect Bi 3+ will be much more stable, so it will not form a pentahalide (removal of the s-electrons is necessary for forming the 5+ cation, and due to poor shielding by d and f-orbitals the s-electrons will be very strongly held by the nucleus.
Non Polar The bonds themselves between phosphorus and chlorine are polar because chlorine is more electronegative than phosphorus.However the molecule is non polar because th â¦ e five regions of electron density are the same.1 person found this useful.he â¦ bond  angles are less than tetrahedral, 93 o compared to  tetrahedral angle of 109.5 o, there are four electron  pairs, three bonds and the lone pair give the molecule a distorted  tetrahedral electron arangement, (VSEPR thoery).
