Label the molecular orbitals formed by the following combinations of atomic orbitals if Z-axis is the internuclear axis.
` 2p_y - 2P_y`

Explanation

To label the molecular orbitals formed by the combination of the atomic orbitals \(2p_y\) and \(2p_y\), we can follow these steps:

### Step 1: Identify the Atomic Orbitals
The atomic orbitals involved in this combination are \(2p_y\) from two different atoms. The \(2p_y\) orbital has a specific shape and orientation, with lobes extending along the y-axis.

### Step 2: Determine the Orientation of the Axis
Since the question specifies that the z-axis is the internuclear axis, we will visualize the two \(2p_y\) orbitals aligned such that their lobes are oriented perpendicular to the z-axis (i.e., along the y-axis).
