Why is the energy of `pi2p_(x) and pi2p_(y)MO s` lower than `sigma2p_(x) MO` in `N_(2)` molecule?

Explanation

To understand why the energy of the π2p_x and π2p_y molecular orbitals is lower than that of the σ2p_z molecular orbital in the nitrogen (N₂) molecule, we can break down the explanation into a series of steps:

### Step 1: Understand Molecular Orbitals
Molecular orbitals (MOs) are formed by the combination of atomic orbitals. In diatomic molecules like N₂, the atomic orbitals from each atom combine to form bonding and antibonding molecular orbitals.

### Step 2: Identify the Orbitals Involved
In nitrogen, we are dealing with the 2s and 2p atomic orbitals. The relevant molecular orbitals formed from these atomic orbitals are:
- σ2s (bonding)
