Vedclass · Answer

(A) The strength of the $P-O$ bond is influenced by the back-bonding from the oxygen $p$-orbitals to the phosphorus $d$-orbitals. Due to the highest electronegativity of $F$ atoms,the $-I$ effect is strongest in $F_3PO$. This increases the partial positive charge on the $P$ atom,which enhances the back-donation of electrons from the oxygen atom to the phosphorus atom. Consequently,$F_3PO$ exhibits the strongest $P-O$ bond.
