Which of the following oxides will be the least acidic?

A

`P_(4) O_(6)`

B

`P_(4)O_(10)`

C

`As_(4)O_(6)`

D

`As_(4)O_(10)`

Text Solution

Verified by Experts

The correct Answer is:
C
Acidic character of oxides decreases down the group. Thus, oxides of As are less acidic than those of P. acidic character increases with increases in oxidation state. Thus `As_(4)O_(10)` (O.S.=5) is more acidic than `As_(4)O_(6)`(O.S.=3) . Thus `As_(4)O_(6)` is least acidic.
