Question

Only those elements of s-block can produce superoxides which have :

• A. High ionisation energy
• B. High electronegativity
• C. High charge density
• D. Low ionisation potential

Answer 1

The correct option is D Low ionisation potential

As the size of the elements increases( ionization potential will be low ) the tendency of formation of super oxides increases.
The super oxide stability increase as the size of the alkali metal increases.
so the elements with low ionisation potential forms super oxides easily.
Hence option D is correct.
