We learned that four new molecular orbitals are created from the p orbitals for each carbon atom in the butadiene molecule (the axes perpendicular to the page). Which statement about these molecular orbitals is NOT true?

The four molecular p orbitals of the four carbon atoms can be lined up parallel in order to create four new molecular orbitals.

The electrons in the new molecular orbitals benefit because they are not confined to just one atom.

The electrons, because of the new molecular orbits, are spread out over the entire molecule.

As a result of the new molecular orbitals, the bond between the second and third carbon atoms is not really a single bond. In fact, the bond should be shorter.
