Question

The wavefunction expression for the antibonding molecular orbital (1σ) in LiH is $\Psi$_{out of phase} = N[$\phi$ _H(1s) - $\lambda$$\phi$ _Li(2s)] where λ < 1.

Quizplus · Accepted Answer

The wavefunction expression for an antibonding molecular orbital should have a positive coefficient for the more electronegative atom's atomic orbital, not a negative one.
