(c) TIPS/Formulae :

(i) Non metallic oxides are more covalent (or less ionic) as compared to metallic oxides.

(ii) Higher the polarizing power of cation (higher for higher oxidation state of similar size cation’s) more will be covalent character.

(i) P2O5 will be more covalent than other metallic oxides.

(ii) Oxidation state of Mn is + 7 in Mn2O7, oxidation state of Cr in CrO3 is + 6 and oxidation state of Mn is + 2 in MnO.

? MnO is most ionic.

NOTE : P2O5, being a non-metallic oxide will definitely be more covalent than the other metallic oxides. Further, we know that higher the polarising power of the cation (higher for higher oxidation state of the similar size cations) more will be the covalent character. Here Mn si in +7O.S in Mn2O7, Cr in +6 in CrO3 and Mn in +2 in MnO. So MnO is the most ionic and Mn2O7 is the most covalent.
