AIIMS 2019 Chemistry Quantum Numbers MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which one of the following set of quantum numbers is not possible for electron?
A
B
C
D
Correct Answer
Option C
Detailed Explanation
In the context of electron configuration, the 4p subshell can accommodate a total of six electrons, with the quantum numbers (principal), (azimuthal), and (magnetic) representing the three possible orientations of the p orbital. The spin quantum number can be either or , allowing for two electrons per orbital. Since option C correctly identifies the possible configurations for a 4p electron, it is valid, while the other options are not applicable as they do not provide relevant information regarding the electron's quantum state.
