Chemistry-Molecular Orbital Theory
NEET Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram showing the molecular orbital configuration of O2. Which statement accurately describes the magnetic property of O2 based on the molecular orbital theory?
A
O2 is diamagnetic due to paired electrons in all orbitals.
B
O2 is paramagnetic because of unpaired electrons in π* orbitals.
C
O2 is diamagnetic because of complete filling of π orbitals.
D
O2 is paramagnetic due to unpaired electrons in σ orbitals.
Correct Answer
Option B
Detailed Explanation
O2 is paramagnetic because it has unpaired electrons in the π* 2px and π* 2py molecular orbitals, which is consistent with experimental observations.
