Question: Which of the following statements is true regarding the molecular orbital theory?

Options:

Correct Answer: It explains the magnetic properties of molecules.

Solution:

Molecular orbital theory explains the magnetic properties of molecules, such as paramagnetism in O2.

Which of the following statements is true regarding the molecular orbital theory?

Which of the following statements is true regarding the molecular orbital theory?

Step 1: Understand what molecular orbital theory is. It is a way to describe how atoms combine to form molecules by considering the behavior of electrons in molecular orbitals.
Step 2: Learn about magnetic properties of molecules. Some molecules can be attracted to a magnet (paramagnetic) while others cannot (diamagnetic).
Step 3: Recognize that molecular orbital theory helps explain these magnetic properties by showing how electrons are arranged in molecular orbitals.
Step 4: Focus on the example of O2 (oxygen molecule). According to molecular orbital theory, O2 has unpaired electrons in its molecular orbitals, which makes it paramagnetic.
Step 5: Conclude that the statement about molecular orbital theory explaining the magnetic properties of molecules, specifically the paramagnetism in O2, is true.
