Question

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

Oxide of AI is amphoteric. SO2 is more acidic than P2O3. Therefore, correct order of acidic character is AI2O3 < 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 acidic strength is

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

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

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

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

Oxide of AI is amphoteric. $S O_{2}$ is more acidic than $P_{2} O_{3}$ . Therefore, correct order of acidic character is $A I_{2} O_{3} < S i O_{2} < P_{2} O_{3} < S O_{2}$
