Which of the following oxides will be the least acidic?
A.
$$A{s_4}{O_6}$$
B.
$$A{s_4}{O_{10}}$$
C.
$${P_4}{O_{10}}$$
D.
$${P_4}{O_6}$$
Answer :
$$A{s_4}{O_6}$$
Solution :
As the oxidation state of central atom increases the acidic character increases, so the correct order of acidic character is
$$\mathop {{P_4}}\limits^{ + 5} {O_{10}} > \mathop {{P_4}}\limits^{ + 3} {O_6} > \mathop {A{s_4}}\limits^{ + 5} {O_{10}} > \mathop {A{s_4}}\limits^{ + 3} {O_6}$$
and hence, \[A{{s}_{4}}{{O}_{6}}\] is least acidic.
