Question

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

While moving along a group from top to bottom, acidic nature of oxides decreases and along a period left to right, acidic nature increases. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-5uumvzx2d2tx.png" /> So, 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

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

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

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

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

While moving along a group from top to bottom, acidic nature of oxides decreases and along a period left to right, acidic nature increases.

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

Q. Among Al2​O3​,SiO2​,P2​O3​ and SO2​ the correct order of acid strength is

Al2​O3​<SiO2​<SO2​<P2​O3​

Al2​O3​<SiO2​<P2​O3​<SO2​

SiO2​<SO2​<Al2​O3​<P2​O3​

SO2​<P2​O3​<SiO2​<Al2​O3​
