a) Explain the relative trends in acidities of the compounds of the formula HXOn for compounds with identical central atoms, X, but differing values of n. For example, how can one explain the differences in acidities between the different HCLOn molecules?
b) Explain the relative trends in acidities for the compounds of the formula HXOn for compounds of identical n but differing central atoms X with respect to another central atom from the same column. For example, how can one explain the differences in acidity between HCLO3 and HIO3?
