# Physical Chemistry MO Theory Description for the H2 Molecule Question

Stuck on a homework question? Our verified tutors can answer all questions, from **basic math** to advanced rocket science!

I’m working on a chemistry multi-part question and need guidance to help me learn.

Compare the MO theory description for the H2 molecule, where the wavefunction is given by equation a:

.ψ=[ψ (1)+ψ (1)][ψ (2)+ψ (2)]

$a.\psi =\left[{\psi}_{A}\right(1)+{\psi}_{B}(1\left)\right]\left[{\psi}_{A}\right(2)+{\psi}_{B}(2\left)\right]$

with the VB treatment given by equation b

$b.\psi ={\psi}_{A}\left(1\right){\psi}_{B}\left(2\right)+{\psi}_{A}\left(2\right){\psi}_{B}\left(1\right)+\lambda \left[{\psi}_{A}\right(1\left){\psi}_{A}\right(2)+{\psi}_{B}(1\left){\psi}_{B}\right(2\left)\right]$

1. What is the meaning of lambda, λ?

2. Under what condition(s) do the two equations become identical?

3. How does the MO theory treat the ionic character contribution to the wavefunction?
