Orbitals of& equal energy are called degenerated orbitals. Homonuclear molecules are the molecules composed of only one type of element and contain following set of degenerated orbitals:

As, energy of,

$\sigma2s > \sigma1s$

$\pi2{p}_{x} \approx 2{p}_{y}$

${\pi}^{*}2{p}_{x} < {σ}^{*}2{p}_{z}$

$\sigma2{p}_{x} < {σ}^{*}2{p}_{z}$

Thus, only $\pi2{p}_{x}$ and $\pi2{p}_{y}$ are degenerate orbitals.
