Identify the most acidic oxide among the following oxides based on their reaction with water

Options

A. `SO_(3)`
B. `P_(4)O_(10)`
C. `Cl_(2)O_(7)`
D. `N_(2)O_(5)`

Answer

C

Explanation

As we move from left to right within a period, the ionisation energies of the elements usually increases and hence, elements usually increases and hence their oxides show a gradual variation from strongly basic through amphoteric to strongly acidic character.
Oxide of more electronegative atom is more acidic in nature.
`underset("Strongly acidic")(SO_(3),P_(4)O_(10),N_(2)O_(5)), underset("Very strongly acidic")(Cl_(2)O_(7))`
