Ph4+ and Nh4+ are both tetrahydrides that have a similar structure, where the central atom is bonded to four hydrogen atoms. However, the formation of Ph4+ is more difficult than Nh4+. This can be explained by the nature of the central atoms and their electronic configuration.
Electronic Configuration of Phosphorus and Nitrogen
Phosphorus and nitrogen belong to group 15 in the periodic table, which means that they have similar electronic configurations. Both elements have five valence electrons, with four electrons in the outer shell and one in the inner shell.
The electronic configuration of nitrogen is 1s2 2s2 2p3, while that of phosphorus is 1s2 2s2 2p6 3s2 3p3. The extra shell of electrons in phosphorus makes it larger in size than nitrogen and gives it a lower electronegativity.
Formation of Nh4+
Nitrogen forms the ammonium ion (Nh4+) by accepting a lone pair of electrons from four hydrogen atoms. The nitrogen atom acquires a positive charge and gets surrounded by four hydrogen atoms that are covalently bonded to it. The overall charge on the ion is +1.
Nitrogen’s smaller size and higher electronegativity enable it to form strong covalent bonds with hydrogen atoms. The lone pair of electrons on nitrogen makes it an excellent electron acceptor, thereby stabilizing the ammonium ion.
Formation of Ph4+
The formation of Ph4+ is more challenging than Nh4+ due to the differences in the electronic configuration of the central atoms. Phosphorus has a larger size and a lower electronegativity than nitrogen, which means that it is less able to attract electrons.
The lone pair of electrons on phosphorus is also distributed differently than on nitrogen. The four p-orbitals of phosphorus form a tetrahedral arrangement, which means that the lone pair of electrons is distributed among them. This makes it difficult for the phosphorus atom to accept electrons from hydrogen atoms and form a stable, positively charged ion like Nh4+.
Conclusion
In conclusion, the formation of Ph4+ is difficult compared to Nh4+ due to the differences in the electronic configuration of phosphorus and nitrogen. While nitrogen has a smaller size and higher electronegativity, phosphorus has a larger size and lower electronegativity, which makes it less able to attract electrons. Additionally, the lone pair of electrons on phosphorus is distributed differently than on nitrogen, making it difficult for the phosphorus atom to form a stable, positively charged ion like Nh4+.
