Vedclass · Answer

(A) The acidic strength of oxides is directly proportional to the electronegativity $(EN)$ of the central atom and the oxidation state of the central atom.For option $A$,the central atoms are $Cl$ $(+7)$,$S$ $(+6)$,and $P$ $(+5)$. Since electronegativity increases from $P$ to $S$ to $Cl$ and the oxidation state also increases,the acidic strength follows the order $Cl_2O_7 > SO_3 > P_4O_{10}$.Thus,the correct option is $A$.
