Question

For a homonuclear diatomic with z as bond axis, ignore radial nodes. Count a transverse internuclear nodal plane when present. Inversion is through the bond midpoint. Use the two lists below and choose the INCORRECT complete assignment.

Symmetry code	Meaning
[a]	bonding, g
[b]	bonding, u
[c]	antibonding, u
[d]	antibonding, g

List-I	List-II
[P] σ(2s)	[1] zero nodal planes
[Q] π(2pₓ)	[2] one nodal plane
[R] σ*(2 $p_{z}$ )	[3] two nodal planes
[S] δ(3 $d_{x y}$ )

TestHub · Accepted Answer

σ(2s) is bonding gerade with no angular nodal plane. π(2pₓ) is bonding ungerade with the yz nodal plane. σ*(2 p z ​ ) has a transverse nodal plane and ungerade symmetry, so R requires 2, c, not 2, d. Bonding δ(3 d x y ​ ) has xz and yz nodes and is gerade.
