Copyright for NIST Standard Reference Data is governed by H H298.15= A*t + B*t2/2 + of all reactions involving this species. French, M.A. Soc. The exchange of electrons between an atomic orbital on one atom and an antibonding orbital on another atom is known as back bonding.. So, in p . So, for a steric number of four, we get the Sp3hybridization on a phosphorous atom in the PF3 molecule. Phosphorus trifluoride (PF3), is a colorless and odorless gas. When phosphorus burns in chlorine both are formed - the majority product depending on how much chlorine is available. Fluorine atoms already share 2 electrons with the help of a single bond so it only needs 6 more electrons to complete its octet rule. The molecular geometry or shape for PF3 is the trigonal pyramid. This repulsion distorts the whole structure where the effect increases to many folds because of the smaller size of fluorine and shorter atomic radius distance. Required fields are marked *. Phys., 1984, 81, 6166. 4 0 obj Steric number is the addition of a total number of bonded atoms around a central atom and the lone pair present on it., Steric number of PF3 = (Number of bonded atoms attached to phosphorous + Lone pair on phosphorous). Its main use is as a ligand in metal complexes. The newly produced hybrid orbitals in PF3 molecule have 25% behavior of the s orbital and 75% behavior of the p orbital. Also, in the PF3 molecule, fluorine is a highly electronegative atom and it fetched more electrons towards itself which also creates more repulsion, and this causes, widening the bond angle in PF3.
