Given below are two statements :
Statement I : Lithium and Magnesium do not form superoxide
Statement II : The ionic radius of is larger than ionic radius of In the light of the above statements, choose the most appropriate answer from the questions given below :
In the light of the above statements, choose the most appropriate answer from the questions given below :
Options
- AStatement I is incorrect but Statement II is correct
- BStatement I is correct but Statement II is incorrect
- CBoth statement I and Statement II are incorrect
- DBoth Statement I and Statement II are correct
Correct answer
D. Both Statement I and Statement II are correct
Step-by-step solution
The values of ionic radii of and respectively. Thus, the lithium ion with charge is only marginally larger than the magnesium ion having a charge of .
The superoxide releases the most energy when formed, the superoxide is preferentially formed for the larger metals where the more complex anions are not polarised. So, do not form superoxides.
Therefore both the given options were correct.
