Hey dear,
● Answer -
c) Cl2O7
● Explaination -
Let's calculate oxidation state of Cl atom in all oxides.
We'll take OS of O as -2 and that of Cl as x.
In Cl2O,
2×x + 1(-2) = 0
2x - 2 = 0
x = +1
In Cl2O5,
2×x + 5(-2) = 0
2x - 10 = 0
x = +5
In Cl2O7,
2×x + 7(-2) = 0
2x - 14 = 0
x = +7
In Cl2O3,
2×x + 3(-2) = 0
2x - 6 = 0
x = +3
Higher the oxidation state higher acidic strength, therefore Cl2O7 is more acidic than others.
* As to your doubt, sum oxidation state of all ions in compound is equal to charge on it. That's why here total sum is taken 0 .
