Q. In a homonuclear molecule which of the following set of orbitals is degenerate?
A) $\sigma 2s\$and$\ \sigma 1s$
B) [image:4_image11.emf]
C) $\pi 2p_{x}\$and $\sigma 2p_{z}$
D) [image:4_image12.emf]
Explanation
(b)
$\pi 2p_{x}$ and $\pi 2p_{y}$ or $\ _{\pi\ 2p_{x}}^{*}$ and $\ _{\pi\ 2p_{y}}^{*}$ orbitals have nearly equal energy and thus, are called degenerate orbitals.
