Phosphorus Trifluoride PF3
Gabriella Bercey 1st Block
The lewis structure of PF3 has 1 phosphorus, and 3 fluorine atoms. Each fluorine shares 1 electron with the phosphorus atom to create octets for each atom. The dots around the symbol is the valence electrons and the lines connecting the atoms is the bonded pairs.
The molecular shape of PF3 is trigonal pyramid. The angle bond of PF3 based on the molecular shape is 109.5 degrees. As far as overall polarity, it is polar.
Phosphorus Trifluoride is synthisized from phosphorus trichloride by exchanging halogens with different fluorides. The example given is zinc fluoride. 2 PCl3 + 3 ZnF2 → 2 PF3 + 3 ZnCl. There aren't any by-products of the reaction.
It had been discovered in 2013 that phosphorus trifluoride can be synthesized from CO dissolving metal reduction.
