Question: In which of the following molecules does the molecular orbital diagram show a paramagnetic behavior?

Options:

Correct Answer: O2

Solution:

O2 is paramagnetic due to the presence of two unpaired electrons in its molecular orbitals.

In which of the following molecules does the molecular orbital diagram show a paramagnetic behavior?

In which of the following molecules does the molecular orbital diagram show a paramagnetic behavior?

Step 1: Understand what paramagnetic means. A molecule is paramagnetic if it has unpaired electrons in its molecular orbitals.
Step 2: Look at the molecular orbital diagram of O2 (oxygen molecule).
Step 3: Identify the electrons in the molecular orbitals of O2. Count how many are paired and how many are unpaired.
Step 4: Notice that O2 has two unpaired electrons in its molecular orbitals.
Step 5: Conclude that since O2 has unpaired electrons, it exhibits paramagnetic behavior.

Molecular Orbital Theory – Understanding how molecular orbitals are formed from atomic orbitals and how they can indicate the presence of unpaired electrons.
Paramagnetism vs. Diamagnetism – Differentiating between paramagnetic substances (with unpaired electrons) and diamagnetic substances (with all electrons paired).
