JEE Main 2023 — s Block Elements Question with Solution
JEE Main 2023 (08 Apr Shift 1)
Question
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 :

Step-by-step explanation
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.
