In a homonuclear molecule, which of the following sets of orbitals is degenerate?

Options

(a) σ 1s and σ 2s
(b) π 2px and π 2py
(c) π 2px and σ 2pz
(d) σ 2px and σ * 2pz

Correct Answer:

π 2px and π 2py

Explanation:

Orbitals having nearly same energy are called degenerate orbitals. Among the given, π 2px and π 2py orbitals are of eqouivalent energy, thus, are called degenerate orbitals.
