Here is the problem:
Which of the following describes why there are two π, two π*, one σ and one σ* molecular orbitals formed from the constructive and deconstructive interference of two p subshells (three p orbitals on each atom)?
A) When two similar p orbitals on the internuclear axis interact, they form one σ and one σ* molecular orbitals. B) When two similar p orbitals perpendicular to the internuclear axis interact they form one π and one π* molecular orbitals.
C) When degenerate orbitals interact in the same way, they don’t form degenerate molecular orbitals.
D) Both A and B
E) A, B and C
The correct answer is D), but I'm not sure why. I've been trying to find info. online but it's very confusing. Any help would be appreciated!
