Current Question (ID: 8112)

Question:

$\text{The correct order of acidic strength is :}$

Options:

1. $\text{Cl}_2\text{O}_7 > \text{SO}_2 > \text{P}_4\text{O}_{10}$
2. $\text{CO}_2 > \text{N}_2\text{O}_5 > \text{SO}_3$
3. $\text{Na}_2\text{O} > \text{MgO} > \text{Al}_2\text{O}_3$
4. $\text{K}_2\text{O} > \text{CaO} > \text{MgO}$

Solution:

$\text{HINT: Acidic character of oxide is directly proportional to the electronegativity of the central atom.}$ $\text{Explanation:}$ $\text{As the non-metallic character of the element attached to the oxygen atom increases, the difference between the electronegativity values of the element and oxygen decreases.}$ $\text{Hence, the acidic strength in a given oxide is inversely proportional to the electronegativity difference between the atoms or vice versa.}$ $\text{So, the correct order of acidic strength : } \text{Cl}_2\text{O}_7 > \text{SO}_2 > \text{P}_4\text{O}_{10}$ $\text{Thus, option 1 is the correct answer.}$
