In the LCAO Wavefunction for H₂ Given Below, the Second $\Psi_{\mathrm{MO}}^{\mathrm{el}}$

question 18

Multiple Choice

In the LCAO wavefunction for H₂ given below, the second term can be described as "ionic" because $\Psi_{\mathrm{MO}}^{\mathrm{el}}$ = [1s^A (1) 1s^B (2) + 1s^A (2) 1s^B (1) ] + [1s^A (1) 1s^A (2) + 1s^B (1) 1s^B (2) ]

• A) it describes the excited state of each orbital.
• B) it has both electrons centered on one nucleus or the other.
• C) it has both electrons equally shared between the two nuclei.
• D) it is a wavefunction that describes two electrons.
• E) the second term is not an "ionic" term.
