Question

As we move down the group in alkaline earth metal, what happens to the ability to form peroxides?

  1. Remains same
  2. Increases 
  3. Decreases 
  4. Group 2 doesn't have the ability to form peroxide.

hintHint:

Down the group peroxide forming ability increases.

The correct answer is: Increases 


    • As we move down the group in alkaline earth metal, what happens to the ability to form peroxides increases.
    • The covalent bond between the two oxygen atom is relatively weak.
    • The electrons in the peroxide ion will be strongly attracted by bigger +2 ions.
