AIIMS 2019 Chemistry Molecular Orbital Theory MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Due to similar molecular bonding, the S₂ molecule is paramagnetic like O₂. It has two unpaired electrons in the anti-bonding t₂g orbitals.

A

True

B

False

C

Cannot be determined

D

None of the above

Correct Answer

Option A

Detailed Explanation

The statement is true because the S₂ molecule, like O₂, exhibits paramagnetism due to the presence of two unpaired electrons in its molecular orbitals, specifically in the anti-bonding t₂g orbitals. This unpaired electron configuration leads to magnetic properties similar to those of O₂. Option B is incorrect as it contradicts the established understanding of S₂'s electronic structure, while options C and D are not applicable since the information provided allows for a definitive answer. Understanding the molecular orbital theory helps clarify the magnetic properties of diatomic molecules like S₂ and O₂.
