Question

Among Al2O3,SiO2,P2O3 and SO2 the correct order of acid strength is (A)  P2O3<Al2O3<SiO2<SO2  (B)  SiO2<SO2<Al2O3<P2O3  (C)  Al2O3<SiO2<P2O3<SO2  (D)  SO2<P2O3<SiO2<Al2O3

With decrease in size from Al to S, the basic nature of oxide decrease and acidic nature increases. Hence, the order of acid strength is as Al2O3 < SiO2 < P2O3 < SO2

Q. Among $A l_{2} O_{3}, S i O_{2}, P_{2} O_{3}$ and $S O_{2}$ the correct order of acid strength is

$P_{2} O_{3} < A l_{2} O_{3} < S i O_{2} < S O_{2}$

$S i O_{2} < S O_{2} < A l_{2} O_{3} < P_{2} O_{3}$

$A l_{2} O_{3} < S i O_{2} < P_{2} O_{3} < S O_{2}$

$S O_{2} < P_{2} O_{3} < S i O_{2} < A l_{2} O_{3}$

With decrease in size from $A l$ to S, the basic nature of oxide decrease and acidic nature increases. Hence, the order of acid strength is as
$A l_{2} O_{3} < S i O_{2} < P_{2} O_{3} < S O_{2}$
