JEE Main Chemistry Class 11 Structure of Atom Part 2 Questions

For A,
Given n=3 and l=3
but we know maximum value of I=n−1.
∴ I can't be equal to n.
So, Set A of quantum numbers is not possible.
For B,
Given n=3,l=2,m=−2
Here, l=2 which follow the rule l=n−1.
And we know possible value of m is −I to +I.
here possible value of m=−2 to +2
∴ This Set B is valid set of quantum numbers.
For C,
Given n=2,I=1,m=+1
Here I=1 which follows the rule I=n−1.
For I=1 possible value of m=−1 to +1
Here m=+1. So value of m is valid.
∴ Set C is valid set of quantum numbers.
For D,
Given n=2,I=2,m=+2
I=2 does not follow the rule I=n−1 rule.
∴ Set D is not valid set of quantum numbers.
