Molecular orbital theory uses one energy order up to $\text{N}_2$ and another for $\text{O}_2$ and $\text{F}_2$. Read two statements about how this order shows in real molecules. Statement I: In the $\text{C}_2$ molecule, both bonds of the double bond are π bonds, because the four electrons after $\sigma^* 2s$ go into the two $\pi 2p$ orbitals. Statement II: If $\sigma 2p_z$ lay below the $\pi 2p$ pair in $\text{B}_2$, as it does in $\text{O}_2$, then $\text{B}_2$ would be diamagnetic.
