Which of the following pictorial diagram most correctly represents the ^* ( -antibonding) molecular orbital between two atoms if the internuclear axis is taken to be in the z-direction ( z-axis )?

Step-by-step solution

To determine the correct pictorial representation of a ^ * ( -antibonding) molecular orbital, we need to consider how it is formed. 1. A molecular orbital is formed by the sideways (lateral) overlap of atomic orbitals (like p-orbitals) whose axes are perpendicular to the internuclear axis (z-axis). 2. An antibonding molecular orbital ( ^ * ) is formed by the out-of-phase (subtractive) overlap of these atomic orbitals. This means the positive lobe of one orbital overlaps with the negative lobe of the other. 3. Visua
