Current Question (ID: 10617)

Question:

$\text{The least acidic oxide among the following is:}$

Options:

1. $\text{P}_4\text{O}_6$
2. $\text{P}_4\text{O}_{10}$
3. $\text{As}_4\text{O}_6$ (Correct)
4. $\text{As}_4\text{O}_{10}$

Solution:

$\text{Hint: The oxide in the higher oxidation state of the element is more acidic than that of the lower oxidation state.}$ $\text{Explanation:}$ $\text{The acidic strength of oxides decreases on moving down the group. Moreover, pentoxides are more acidic than trioxides. The oxide in the higher oxidation state of the element is more acidic than that of the lower oxidation state.}$ $\text{So, } \text{P}_4\text{O}_{10} > \text{As}_4\text{O}_6 \text{ and } \text{P}_4\text{O}_{10} > \text{As}_4\text{O}_{10} \text{. Due to an increase in O.N. of an element acidic nature increases. Thus decreasing}$ $\text{order of acidic strength is } \text{P}_4\text{O}_{10} > \text{P}_4\text{O}_6 > \text{As}_4\text{O}_{10} > \text{As}_4\text{O}_6$
