Question:

$\text{Among } \text{Al}_2\text{O}_3, \text{SiO}_2, \text{P}_2\text{O}_3 \text{ and } \text{SO}_2 \text{ the correct order of acid strength is:}$

Options:

1. $\text{SO}_2 < \text{P}_2\text{O}_3 < \text{SiO}_2 < \text{Al}_2\text{O}_3$
2. $\text{SiO}_2 < \text{SO}_2 < \text{Al}_2\text{O}_3 < \text{P}_2\text{O}_3$
3. $\text{Al}_2\text{O}_3 < \text{SiO}_2 < \text{SO}_2 < \text{P}_2\text{O}_3$
4. $\text{Al}_2\text{O}_3 < \text{SiO}_2 < \text{P}_2\text{O}_3 < \text{SO}_2$

Solution:

$\text{Hint: More is the electronegative difference between a central element and oxygen less will be the acidic character.}$ $\text{As the electronegativity difference between element and oxygen decreases the acidic character of oxides increases.}$ $\text{The electronegativity also increases with an increasing oxidation state.}$ $\text{In general, as the non-metallic character increases across the period, the acidic character of their oxides increases.}$ $\text{Thus, the correct order is } \text{Al}_2\text{O}_3 < \text{SiO}_2 < \text{P}_2\text{O}_3 < \text{SO}_2$
